Any time this defense played a good QB, it got sliced and diced for the most part. Hell, Chad Henne made us look silly. Was that due to the lack of pressure and/or scheme OR the personnel and it's immaturity/miscommunication? I think it was a combination of both. Yes the defense blew assignments and showed its inexperience at times, but is that scheme really the best type of D to defend in this new NFL? As I said in the post above, it is a defense playing the percentages relying on the fact that the opponent will eventually make a mistake and in a way "beat themself." It seems like the QB's are getting better and better as an astonishing 10 QB's passed for more than 4,000 yards. That shows me that the passing game is becoming much more prolific and more and more QB's are becoming adept at throwing with precision and making intelligent decisions.
I don't think that "monster" OLB is an absolute need, but I do not see how it can hurt at all. Having a guy of that caliber will demand double teams and, in essence, will open up room for the other pass rushers to operate. I don't think this defense is built for the "elite" OLB type anyway. The Pats are never really going to have a guy with 15 sacks like a Ware because their OLB job is to engage their blocker and read run/pass and then react. Guys like Ware, Merriman, Woodley, Suggs etc. are all just coming after the QB on most plays, not having to worry about 2-gapping.
