Teach him the crowther block. If the play is to his right, Fire step right, 6" power step ata 45* degree angle with his toe pointed up field, not a veer step. Throw his left flipper into the thigh right below the waiste of the defenders near leg to the play. Take his other hand and strike the playside hip of the defender. Teach him to Pound his knees in the ground. It's all about first step with line play. Deliver the blow with the flipper,low, then punch the hip as you drive unsquaring the defender from his gap.
Once you 'Fire step to the play, Deliver the blow, Punch the hip , Pound the knees and once you punch that hip and turn him get your butt to the hole and Drive! The whole key is If you cant or are not strong enough to drive him By punching that playside hip and unsquaring him and getting your butt to the ball even if you can't whip him you have walled him off creating a running lane. I have a whole video tape series on this.
Control the hip,Control the man.

What happens if it is a straight run and the lineman is using a bull rush, nothing fancy? I have taught him the swim move and angles, is that the correct thing to do when dealing with the straight ahead rush from a bigger, stronger lineman? My son seems to handle the big guys easier when he takes the angles, but is using the swim move more effectively the last couple games. There are only a few players bigger than my son in his age group, and he is done playing them for this year. He plays against teams that have lineman that he has handled well in the games earlier this season, so what should I have him working on? What is the best stance on defense for a DT? I have seen 3-point stances and 4-point stances?
