Of course we need to have a base 4-3 defense. However, I think we need to fit our team to the type of opponent we face. So, for example, when we play run heavy teams like the Titans or Jets I say we bring out the ol 5-2. 1) The 5-2 The 5-2 is a line with 5 Dlineman and 2 LBs. In this run heavy formation we could use funneling systems. We could stack one side of the DL to have big time rushers (Mario, Barwin, Mitchell) and then have strong run stoppers with penetration ability on the other side (Okoye and Smith). Or vice versa and swap in appropriate names. We could funnel it both ways towards our strength on the field. Clearly the drawback would be against the pass, but then again, we wouldn't use this formation against the pass anyway. 2) The 4-4 Another good defense against a strong running team like the Jets or Titans. In this formation we have 4 DL and 4 LB. So, now, the O line has no idea where the pressure will come from. Lets take a quick look. Mario---Smith---Amobi---Barwin Cush---Sharpton---Meco---Diles Quinn----Pollard----Jackson In this formation(for a run heavy team) clearly we are going with a running prevention defense. The D has no idea where pressure will come from. Of course, as you can see, Peyton would crave this up. So we would not use this D against the Colts. 3) 3-5-3 A different formation that is designed to throw a different look. I would start this off as a "traditional" 4-4 and then at the snap, one of the lineman suddenly drop back and become a LB. I think Barwin is probably the best candidate for that job. The 46 Being a Defensive football fan I have always loved the ol 46. I think we need to use stunts and different formations to confuse defenses. With out better personal we can now consider using more exotic Jim Johnson types of schemes.
