If there is a problem with your wedge play, start by going back to the basics with the wedge teaching progression in chapter 10 of the book.
Many youth football coaches just go from step one to seven in five minutes and then wonder why their wedge plays don�t work very well. The players need to get comfortable and proficient and perfect each step of the wedge progression from the first inside step to the shoulder to rib cage etc etc.
We often find even youth football teams that wedge well fall off later in the season because the coaching staff thought that since the wedge had worked so well they didn�t need to practice it. I fell into that same trap in 2002. We were averaging nearly 10 yards per wedge play, so we didn�t practice it much weeks 6 and 7. We saw our wedge suffer in the week 8 game, so we went back to repping it for 10 minutes each practice and saw marked improvements.
You can also add some of the troubleshooting methods we discuss in Chapter 10. If you see players coming off the wedge to block a defender, run your wedge on air and have coaches with shields try and get the linemen to come off the wedge to block them. The players need to know their job is to block their own players to their inside, not block the opponent.
If you have problems with the fit, go back to the original fit and freeze step. We have even used Hugh Wyatt�s eyes shut method where we form and fit the wedge with eyes shut. It forces the player to lean into the player to his inside for support. We then have them run the wedge downfield with eyes shut, it forces them to stay connected.
