Double Wing Power Plays and Transferring Drills to 11 on 11

After the wedges, 38, and 29 Sweeps, I put in the power plays. 88/99 Power and Over 88 Power/Under 99 Power.
Along with putting in the plays I'm trying to get drills we work on in break down sessions in practice to transfer over to 11 on 11. One way I try to accomplish this is, for example, breaking down the creation of a good edge with the pulling guards and lead block by the B back. Immediately after the breakdown session I go into 11 on 11 with an emphasis on the offense. I then try to focus on the skill we just worked on. I'm always amazed, but really shouldn't be, when the first couple of plays the guards and B back go where they are supposed to but make contact with absolutely no one. I always wonder why they think I'm having them pull or lead the play. They honestly don't know where to look when its 11 on 11. So I break the skill down and then immediately apply it to 11 on 11 and correct, showing them where the people they are supposed to block are coming from.
Any ideas on how to get skills worked on in drills to transfer to 11 on 11 would be appreciated.
