Basic Double Wing Formations
These are the three basic formations I'll use throughout the season. They are simple, easy to learn and remember during a game. I feel these formations allow us to do a few things play calling wise, and deal with a substitution situation. In middle school football you will have some kids who are not very big -ok, they're small- and I need places to put them on the field to keep them safe (We do not have weight limits). Going Over or Under allows us to split out a smaller kid. He's on the field and he's not in tight in a situation that he is not going to be successful. From his split position he has a good angle to block a linebacker (he usually just slows him a little) on a sweeps or to clear an area of the field for an inside receiver (A or C back). Incidently, the corner will often follow him inside on sweeps too, which opens up the outside. If our opponent begins to ignore the threat of the split end, I send in an athlete for a play who is a threat and I have a play call to take advantage of the situation.
I like to keep it simple for the players and through formation get players onto the field in the best position for them to experience some success.

This isn't the NFL
When you watch kids play football on the playground often its everybody out for a pass and rushers required to wait the agreed upon amount of time ("Mississippi's" in my area). Ninety-nine percent of the plays are passes. Blocking is nonexistent.
Kids need to realize some of them will play the line and you have to convince them they are very important positions. It really helps if you truly believe that and the kids will gauge how much you believe it by the amount of time and the attention you give to teaching linemen in practice.
Kids need to know that they will get bumped and bruised. Begin teaching the difference between a bump, bruise, or scrape and a real injury. Be patient with kids on this point and treat all their concerns as injuries (to be on the safe side). They will begin to see the difference with experience. Its been interesting that every season when full contact begins, one or two kids decide they don't want to play anymore. I encourage kids to stick it out and nothing I do is designed to "weed out" kids, but regrettably some decide the game isn't for them.
Most plays will be runs. A lot of kids want to be wide receivers. I tell them "that's great, but we don't have a position called wide receiver." Maybe some of you can move the ball consistently at the middle school level with the pass. I've found if we pass more than 5 times a game we're in trouble, because we can't move the ball on the ground. In one season (5 games) we threw 18 passes 12 were completed (9 for 2pt conversions and 1 touchdown). We were 4-0-1 that season.
As much as we as coaches understand it, the kids need to know that we are not going to play run and gun football. I'm not taking the fun out of the game for them, but simply trying to give them a realistic picture of what the game will be. Then I work on making the game, in that context, fun for them.

Its Not the Drill
Drills certainly can help us be efficient with our teaching, do a good job of breaking down a game skill so that it transfers to the game, or develop good fundamental habits. However, it's not the drill. It is how its used, who uses it, and who is executing it. The drill doesn't teach, the coach does.
How is the drill used? Ask yourself the question "does what I'm having the kids do directly relate to what they will do on the field?" Now I'm sure everybody is saying of course all my drills directly relate to the field. Let me give you an example. How often in a game does a running back have to get up off the ground (from laying on his back, facing the opposite direction he wants to run), turn around, and then avoid a tackle. Some will know the drill of which I speak. Or how about "Bull in the Ring." Don't tell me about teaching toughness either. Better, in my opinion, for teaching tackling, running back techniques, and, yes, even toughness is a rather simple drill. Line up a ball carrier and a tackler one yard apart. On the whistle it's basically play football. There's no restrictions on the running back. Now, do we see these skills in a game: a running back must avoid a tackler or run low into a tackler and keep his feet moving; a tackler must make the tackle in the open field; and both need toughness to achieve their objective. I know its not the "next big thing," but it efficiently teaches and allows coaches to evaluate football related skills.
Who uses it. Basically, I'm talking about the teaching skill of the coach. The best drill taught poorly produces poor results. Conversely, a poor drill ran by a great teacher will produce better than poor results - I won't go so far as to say great results and why would a great teacher use a poor drill? But you get the idea. My point, hone your teaching skills. My main reason for writing here is to reflect on what I do and, hopefully one day, get feedback to improve.
As coaches we can control the drills we use, how we use them, and how well we teach them. I don't like to think about this one, but we can't always control the talent level of the kids executing the drills. I want to think my coaching has some impact on the game, but deep down I know talent level does have an impact on the scoreboard. I don't think it has much to do with how successful a practice, game, or season was. And I REALLY struggle with this one. We all have ego and pride, and that scoreboard is big and it is lit up for all to see. Try to measure success by how much the kids got out of the experience. Did they get the absolute most out of their ability? (This is as much for me as anyone else and if anyone has a really good handle on it PLEASE let me know how you did it)
Don't look for the "next big thing." Stay true to what you want to accomplish and evaluate any potential new drills or concepts by how well they fit with what you want to get done. Then learn to be really good at teaching the drills you do use. And remember, success isn't always reflected on the scoreboard (I'll try to remember that too).

A Good Start
The cliche would be "setting the tone." I think establish authority would be more accurate. You establish authority by being organized, having a plan, and following through. Being organized is knowing where everything is that you will need for the practice, lesson, season etc. Having a plan is knowing when to use what you will need. Following through is doing what you say you're going to do. If you tell the kids you're going to get a new piece of equipment, you better deliver. If you say you'll have them do "extra work" in practice for being late, you better make sure they do the "extra work." Extra work is often equated to running and sometimes it should, but try to be more creative than that.
Following through might be the most important of the three. They (and the "they" can be parents as well as the kids) are always watching your reactions, and some (unfortunately, you can include parents in the "some" too) will test to see if you really mean it. With discipline, I don't recommend warnings, especially early in the school year/season. Calmly, unemotionally follow through with what you said would happen if a rule is violated. However, effective organization and planning will cut down, but not eliminate, the need for discipline. There's no doubt in my mind that kids want structure, despite what they may be showing outwardly. Its anecdotal evidence, but I've heard kids complain about teachers or coaches who give a freer rein, as much as they complain about those who they perceive as stricter. I know kids don't want to have their time wasted either. If you do an activity that's meant to kill time, don't kid yourself, they will know. They won't like it, and they will act out because of it.
That first day you have those 25-30 eager, energetic faces in front of you, be organized, have a plan, and follow through. Then you'll have the confidence to speak with a clear, strong voice giving specific directions for activities that have direct relevance to what you and the kids want to accomplish. And if the need for flexibility arises, I've found it easier to be flexible when a detailed plan is already in place.

Connecting the Classroom and the Athletic Field
I get special education students who are good athletes, but their disabilities often hinder the success they could have. One of the most rewarding parts of my job is to have a kid, who hasn't always experienced success in school, find success on the athletic field. Athletics can then serve to extend this student's motivation to improving academics and maintaining appropriate behavior in the classroom. Athletics can be another tool for inclusion of special education students with general education students.
I'm constantly seeking to maintain the connection between my teaching and coaching positions. It is important to see your athletes interact with other students and get a more complete picture of who they are as people. Likewise I think it can be useful for others to see how kids are in the athletic arena. For coaches who are not teachers I would encourage you to get involved in some way with the school.

Equipment/Uniform Day
Handing out equipment efficiently actually begins at the equipment turn in day from the previous season. Hopefully, you had your players turn in complete sets of knee, thigh, and girdle pads athletic taped together. Now you can simply hand, or have a player pick up, a complete set.
Remember, half of these kids have not put on pads before; they do not know what a helmet feels like on their heads. As far as the coaches can tell the helmet could be a good fit, but the player feels uncomfortable. We try another helmet, still uncomfortable. Try another...and another. Inevitably he ends up with the original helmet - patience and understanding.
Shoulder pads need to be inspected for size too, which takes a coach's time. Meanwhile, confused players fumble around guessing where all these new pads go. Have you seen the kid with the tail bone pad in the front? Then you know what I mean. Of marginal help for this situation is to have the experienced players help the first timers. However, they're also preoccupied with making sure everything they received fits.
Before you even get started demonstrate where every pad goes (realize though that they are so excited to get pads that you might as well be talking to the wall). So, how does this process work. One coach hands out and fits kids for helmets. Simultaneously, another coach is fitting kids for shoulder pads. The rest of the team is moving through stations picking up a pair of practice pants (lay them out and label stacks by size); a belt; a complete set of thigh, knee, and girdle pads; a practice jersey (again, lay them out and label stacks by size); and a mouth guard. While waiting for a helmet or shoulder pads, players are to put their pads in their pants. This is when knee pads end up in thigh pad pockets and the infamous tail bone pad ends up in front.
With everybody in possession of a pile of equipment, coaches move through the group offering assistance and answering questions with responses such as, "no, I don't know where your thigh pad went" or "it doesn't matter what your practice number is." I wish our practice jerseys weren't old game jerseys.
The session is wrapped up with the whole team, wearing their complete ensemble, touching each piece of equipment as you call it out. The next day's exchange will go like this:
Player: "I didn't get a belt."
You: "why not, you were supposed to take one or say something after we went through all the equipment yesterday."
Player: "I didn't think I needed one."
PATIENCE AND UNDERSTANDING
*I truly do enjoy middle school kids. The energy and excitement they bring can be contagious. They also bring a smile to your face if you look at them with patience and understanding.

I Really Don't Mean to Make It Sound Simple

Thoughts on Special Teams
By the nature of their age and development, some kids are going to be capable of more than others on the football field. However, its important to keep all the kids interested in the sport and give them all equal attention and instruction, because it is impossible to see what type of students and players they will mature into when they reach high school. I've seen the slightly over-weight, non-athletic 7th grader turn into the 6'4" solid 225lb college recruited player as a senior.
What do you do with those non-athletes in middle school, when you still want to be competitive and you want everybody to experience some success, feeling that football was a good experience? We're really trying to do it all here, and in some respects that is impossible. But, we try anyway.
First, I don't dump weak kids on the offensive line. We do pull linemen so they do have to have some athletic ability. That being said when choosing between two decent size kids who probably won't play one of the back positions I try to have the better athlete play defense. I'll also sometimes convince a really good athlete, who is a reserve backfield player, to play one of the guard spots, by rewarding him with ball carries throughout the year.
This was supposed to be a post on special teams. Punt team, my recommendation is don't punt. I'm being serious; I've gone an entire season without punting and in others only punted 2 or 3 times. If you do have to punt (I don't even punt if its 4th and long at midfield), your center should be able to be taught to long snap the ball 8-10 yards. Have your best punter from the starting backs be the punter, and the rest of the team in a tight punt formation of your choice. Tell your punter when he gets the ball to just get it out of there. We practice punts the night before every game, but I don't get anymore complicated than that.
Punt return is even easier. Your best ball carrier drops back as a punt returner. Have a "fire" call when the ball hits the ground, nobody wants to touch fire, so nobody touch the ball when you hear the returner yell "fire," "fire."
The kick off team needs to be stocked with your fastests, best tacklers. You can put two of your non-athletes on the kick off team. Just don't put them next to each other. I put the best tacklers in the middle, on each side of the ball. We do want to be competitive and a weak kick off team gives up touchdowns. Another point, we want all kick offs to be on the ground, preferably ending up between the sideline and the hash mark. We do not want the kick off to go high and deep to the back men. Who do your opponents want to carry the ball? - the two deep men. We can control whether or not they get the ball. They won't be getting the ball. You'll be surprised how many of these kick offs you will end up recovering.
The kick return team is the unit I put a few more of my non-athletes. I place them on the front line of 5. My second line of 4 includes back up receivers and backs, kids who can handle the ball. The back two are, obviously, the two best ball carriers. I assign each player a kid to block on the other team. I haven't been able to make the wedge work in middle school. Nobody seems to block. When they are each assigned a person to block, they at least momentarily slow down the opponent .
It is also vitally important that you teach the kids the rule differences concerning a live ball between punts and kick offs (A few years back I had a kid shuffle around a kick off, waiting to down the ball). They need to understand that when we are receiving a punt, it is our ball unless we muff it; and, on kick offs, the ball is live and up for grabs after 10 yards. Incidentally, before 10 yards, it's just like a punt. They need to understand these rules.
This has been a brief overview on my philosophy of putting the team together. Whole books have been written on each of these topics and it really isn't as simple as I try to make it sound. Hopefully in future posts we'll discuss in more detail what we do with our team.

Final Preparation for the First Game
There's different ways to set the huddle. I just use a simple circle. After the huddle is taught, it's time to practice setting up a huddle after a play and running in plays with substitute. The varsity coach at my school is very good about letting us use the game field to practice. Generally, I have two or three left ends who alternate taking in plays. They know as soon as the play is over to head off the field and come right to me. I had to teach them this. When I first started coaching, the first time the end ran off the field he disappeared in the crowd. When it was time to send in the next play he was nowhere to be found. Anyway, on the game field we'll start at mid-field with the team huddled up. I'll send in the play, they'll line up, run the play with everybody sprinting 10 yards. The ball will be spotted 5 yards from the previous spot. The center will have to set the spot for the huddle (7 yards from the ball), yelling "huddle" with his arms up. The next play will come into the game, the quarterback calls the play in the huddle,the team lines up, runs the play, sprints 10 yards, the ball is spotted 5 yards downfield from the previous spot. We repeat this process five yards at a time until the team reaches the end zone. We enforce any false start penalties and illegal receiver down field penalties on pass plays. We also practice sending in substitutions for other positions. I think the kids are also getting accustomed to driving the ball down the field by having to run 10 error free plays in a row.
When we have the big field we'll also practice transitioning from offense to defense and vice versa. We always want to be ready for the proper 11 players to get on the field. After substitutions have been made, it can get confusing for kids when you yell "offense" and its time for them to be on the field. Their question is "does the starter go into the game or do I go in because I was on the field the last time we were on offense?" I've struggled over the years with how to make this situation less confusing for the kids. What we do right now is have two possible calls when making the transition from offense to defense or vice versa. I can call "last offense," which would be the group that was on the field the last time we were on offense or "starting offense," which would be the starters. It doesn't work perfectly. Sometimes kids forget they were on the field the last time their group was on the field. The kids coming in from the sideline need to echo the call to the players who are on the field at the time of transition so they know who needs to stay or get off the field. One situation to take into account is if a starter gets injured and cannot continue. I try to remember to tell his substitute he is now the starter. Notice I said try to remember, yes in the heat of the game I can forget. It is a lot for kids to remember, but if they are truly into the game and want to play, they will get it.
So, a couple days before the first game we practice these scenarios: changing from defense to offense with "last offense" and "starting offense" and "last defense" and "starting defense." I do take pride in the fact that even early in the season we rarely have to take a time out for too few or too many kids on the field. I also let all the kids know that on offense the quarterback is in charge on the field. If he counts twelve in the huddle (and he's supposed to count on each transition), and he tells a player to get off the field that player is to immediately get off the field. If there is an argument, the quarterback is supposed to call time out tell me who argued and that player doesn't play the rest of the game (incidentally, its never happened in a game that somebody has argued with the quarterback).
I know early in my career I never thought to practice these parts of the game. I just kind of assumed everybody would know when they were on the field and how to shuttle in plays. Believe me, if you practice it you're team will look very organized and I do think organization shows up on the scoreboard.

Priorities for Putting in the Offense
With a staff of two, I am the only coach available for putting in the offense and running the offense specific drills, which influences my priorities and how I teach each priority. Hopefully, you will have more coaches available.
Priority 6 Basic ball control and blocking techniques
The first two skills I teach is how to properly carry the football. Earlier in my coaching I neglected this skill. Kids will carry the ball in any number of ways. You can teach whatever method you like (I prefer the high and tight technique - see Univ. of Wisconsin RBs). I then I have to teach a basic fit and drive blocking technique, and show them what holding is and how not to do it (hands inside the frame of the opponent). I practice this with blocking dummies and then live with partners. As an aside, I really wish I had more time in practice to teach the finer points of techniques and fundamentals, but remember, these kids have a game to play soon. I basically need them to fire off, make solid contact, and maintain contact.
Before we move on to the next priorities, its important to think about which plays you'll need to run for the first game. Basically, you'll need and inside run, outside run, a counter play, and two passes. Each run to the right and left. Don't laugh, you cannot get more complicated than that. That is 10 plays and that will be a lot. They are going to have to learn your play calling terminology also.
Prioritiy 7 Combine the snap with a handoff, teaching the proper way to receive a handoff
Your centers, quarterbacks, and fullbacks execute an inside running play. In my situation with split the team. Half are working on offense, half on defense. So, I have a group of 15 +/- kids. We have around 3 groups working together. At this point, the centers and quarterbacks have begun to step forward. At the end of practice 6 kids will have worked at center and 6 at quarterback. I let everybody else have a chance to play fullback. This is not a minor point. After a practice or two nobody can say that they weren't at least given a chance to play the "glamour" positions. Its obvious some kids won't play the ball handling positions, but they have been given the opportunity.
Priority 8 Execute the inside run against air then against dummies at the point of attack
We're beginning to put all the priorities together now. You should have a pretty good idea which kids will fill certain positions. Put the team in formation (proper stance, staying still), the quarterback calls the cadence (getting off on a snap count), run the play with everybody sprinting 5 yards. Now I teach them the number for each hole (if you number holes, this is the time). Our inside play is 2 Wedge. After a few reps against air, I add blocking dummies in front of the center and guards and teach the wedge block (I'm not going to go into the techniques here).
Priority 9 Execute the outside run against air then against dummies at the point of attack
Same as priority 8, put the team in formation and run your sweep. Then put blocking dummies at the point of attack, both to the right and to the left. At this point you should be putting in your blocking scheme too.
Priority 10 Execute your counter play against air then against dummies
For the first game your counter play may simply be a quarterback bootleg off your sweep. Thats okay, in youth football it can be very effective. However, since that is very easy to teach, I usually teach a sweep off of a fake up the middle. We're faking a wedge and running wide (Buck sweep).
Priority 11 Teach your pass plays the same way a hand off is broken down
Quarterbacks and centers have emerged. Now teach your two basic pass patterns in 3 groups with everyone getting a chance at the receiver positions. Again, this is not a minor point. Every player should at least be able to say they have been given a chance. I would discourage you from putting in a drop back pass. Middle school linemen cannot give the time needed and middle school quarterbacks cannot see past the chaos going on in front of them to find a receiver. All my pass plays are sprint out or roll outs. Particularly effective are waggle plays off the buck sweep. The quarterback is in space and he has the option to just keep running if the receiver forgets to run his pattern (yes, it does happen). One other thing, don't require middle school quarterbacks to make reads. Connect the dots for him. One receiver, he'll be in this spot, throw the ball. Okay, the one read he can make is whether or not a defender is on the receiver, in which case take off running forward (yes, you must specify forward or he'll take off backwards trying to buy time).
Priority 12 Run some plays against a live defense
Its time to put it all together and see how it works. Remember there's a game coming up soon. You won't feel ready to go 11 on 11 and probably aren't ready, but you need to see what adjustments need to be made when plays are run against a live defense. If you want to give the offense some confidence and make a teaching point to the defense, for your very first 11 on 11 play run a quarterback bootleg. Typically there's no one within 10 yards of him as he turns up field. Thats not a bad play call for your first game either.
Have I left a lot out, definately. Remember the time crunch I'm working under. If you are blessed with more time, I think the priorities still hold true. You can just spend more time and go into more detail when teaching them to the team. We're still not ready for a game, but we're getting closer.

Time to Think About Football Season
My situation has a unique challenge, only 5 or so practices in pads before the first game or scrimmage. I don't agree with it, but thats what we have to work with. This situation makes it vitally important that practice is prioritized for what the kids need to know to compete in a game. However, I think the priorities are pretty universal regardless of the situation or offensive system used. The following priorities will deal primarily with the offensive side of the ball.
Priority 1 Safety
Some of these kids will be putting on helmets for the first time. Make sure of a proper fit. If you're not sure what a proper fit is, find a qualified person to show you or help.
Take the helmet out of hitting. I do not teach to lead with the head, hit with the head, or hit someone in the head.
Teach them to keep their heads up during all actions (tackling, blocking, running).
Priority 2 Proper Stance then take off on a snap count or ball movement on defense
To play offense this is a very basic fundamental, get in a proper 3 point stance, stay set (perfectly still), and take off on the proper snap call. I tell the kids "if you can't do this you can't play offense." Everyone wants to play offense, so that usually gets their attention. I usually teach this skill in a large group format, but what how you teach it is secondary to the fact that they have to get it. The first time you teach this, kids will be bouncing up and down in their stances, falling forward before the count, jumping early, being anything but still. Every year I think it will be different. I'm still waiting for that year. A small but important point, don't forget to teach them that once their hand goes down on the 3 point stance they cannot pick it up (according to high school rules) or it's a false start. Thankfully referees have typically given warnings on this early in the season (this is a teaching situation after all), but you may run into the guy who calls it all like it is the state finals (believe me, never a good thing at the middle school level, but it happens). Just for fun, check how often this fundamental is messed up in a pro or college game. It will start to drive you crazy how often it is.
Priority 3 Find your centers and quarterbacks and get them practicing snaps
Obviously, if you can't execute a snap, the best plays begin with everybody trying to recover a fumble. That being said, this priority takes some selling, not for the quarterbacks (you'll have plenty of those), but for the center. Nobody will want to play center. I usually start by asking the whole team which position they think is the most important. The answers usually are quarterback or running back. Then I ask who starts each play with the ball. Again the answer is often quarterback, but a few catch on and say the center. Now I play up, but I do truly believe it, that the center is the most important position on the offense, because without a good snap and a solid, strong blocker up the middle none of our plays will work. I then tell them that if they want to never come off the field when we're on offense, then be our best center. We usually find a couple then ,and you need to find, at the bare minimum, 3 kids who could do it in a game. Teach your technique for snapping and receiving snaps and have them practice it.
Priority 4 Line in a formation and everybody know the names of each position
This is actually closely related to priority 5, but deserves its own attention for one very simple, but important when in the middle of a game, reason - substitutions. Whatever formation you play, the kids need to know it and the names of each position. I would only have one formation for the first game (only 2-3 variations of it thereafter). For example, you need to be able to send a kid in the game to play right guard and have him know where to line up. DO NOT assume kids already know the names of the positions. I have made this assumption and it does not look good in a game.
Priory 5 Line up in a formation and on a snap count, make a snap to a quarterback and everybody take off from a proper stance
This is related to priority 1; however, just when you are feeling good about their mastery of priority 1 and you add the steps of a formation and an actual count and snap, it will all fall apart at first. Remind them of the rules concerning false starts and the fact that they won't play offense if they can't do it within the rules. Keep giving them repetitions and priority 1 will mesh quite nicely with the two new added steps. This is also a good time to teach your spacing between linemen. The spacing you choose isn't important (I do have my preferences - foot to foot or 6 inch splits); however, you do need to teach everyone how to establish line splits consistently. Simply telling them doesn't work, because your center will be over the ball and your tackles will establish themselves 1 foot away from him. Now, where do the guards go? They will try to fit and get into a stance in that 1 foot gap. Make sure they establish positions in order, center over ball, guards, tackles, tight ends. Then check to make sure the line is straight and nobody is lined up off sides. You need to give repetitions to lining up correctly. Have them line up, correct as needed, have them get up, send them back 5 yards. Then have them come back up to the ball and line up again.
These priorities may seam quite simple, and they are - to us. They are the beginning point to running an offense and the kids that do get them the fastest actually receive the first look for playing on offense (make sure the fastest kid gets it). These priorities need to be reviewed and practiced throughout the season. Now, we haven't even run a play yet, but without these first five priorities, you never will run a play. Running the offense has another set of priorities that I'll share in the next post.
