I don't know if Pettine is the founder of the D but I like Buffalo's base. They play a straight 4-3, but with Buffalo, that Jerry Hughes is is a great hand at that DE/OLB position. He plays like a DE on some snaps and OLB on others. This could be Nick Perry's natural position. Nick is a tweener guy. That type of scheme could play right into his strengths.

In a vanilla 4-3, you have to get your pass rush heat from DE's. Those kind of guys are hard to get.

A combo set-up could be installed here without shaking up our roster as much.
