I-form Tight and anyone outta strong formation work well too motion the te and fb sometimes make the D think, slide protect to your advantage and try the HB Direct snap, and fb dives to help establish a run game. use bush on counters and toss's, although keep toss's to a minimum i find them to be relatviely unsucessful.
good luck if u wanna lab and your on 360 hit me up
i need someone to lab with i gotta work on my D with kids who dont exploit, need to find some good run stoppers and stuff like that if not im changing my D PB again :/
