Bill Belichick is arguably one of the best x's and o's coaches of all time, fans from other teams would even have a hard time refuting that. I have read a few books that dealt with Belichicks coaching and it had been mentioned that while he was an assistant all those years back, that it was he who really brought the 3-4 defense to what it is today. With the success of the 3-4 defense in recent years, other nfl teams are starting to run it, in fact the amount of teams has increased to about 1/3 of the teams in the NFL. Could there be a case for Belichick trying to configure a whole new wrinkle into how to play defense. I am not saying that it will be this completely new defense all together, but whats to say that there are not some wrinkles in both the 3-4 and the 4-3 that have yet to be explored. Most people will argue that D-lineman are the hardest position to find quality players at. With what seems to be a stockpile of high round talent at the position, maybe BB has something new in mind. I am not as football smart as many of you, but what I have learned while watching this BB run team is that you should never pigeon whole them into one thing or another. I have a feeling we could be sitting here next fall talking about what that type of defense is. I also think that the offense could be going through a similar transition, look to see the TE and Fullback really take on a whole new role. Just a thought.
