Consider the roster changes since last December. Is is possible that Belichick is moving to an exclusive 4-3? Did he decide on this switch even before the draft? It makes sense that he would switch to a 4-3, since disciples McDaniels, Mangini, Pioli have all switched to a 3-4 defense and compete for the same players. There may now be better value for BB to go after 4-3 players. We traded for Burgess, drafted Brace, signed Banta Cain, and kept Jarvis with his 5M cap hit. Wilfork is/was a beast as a 4-3 DT in college. With Seymour now gone (a brilliant move by the way, if the future CBA sets low fixed salaries for top draft picks), and on top of Bruschi and Harrison retiring, I'm not even sure if the Patriots have the personnel to play 3-4 anymore. It's looking like we'll be using Jarvis, Burgess, Banta Bain, and Warren at DE, with Wilfork, Brace, Wright, Pryor at DT. We have three fast LB's in Mayo, Adalius, and Guyton. By the way, for those worried about missing Seymour, the Pats went 8-0 without Richard Seymour in 2007.
