New England (7) For years, Bill Belichick's defense has been built around linebackers. Those days are over, and by far the best unit on this defense is the defensive line. Richard Seymour is an extraordinary football player, but a season ago, he became invisible at times. Fortunately, fellow starters Ty Warren and Vince Wilfork rose to elite levels.

Wilfork has joined the short list of outstanding nose tackles, the type of player who can completely change a game without making a single tackle.
