Wilfork is a great guy who really epitomized (together with people like Brady and Edelman) why the Patriots can win year after year. He was highly skilled physically but at the same time he understood the nuances of the game: smart, good decisions under pressure, magnetic leader, with tremendous internal integrity and character. It's these elements of character and intelligence among their top players that set the Patriots apart from other teams. Every head coach can draft for size and speed, but BB is the only one who can consistently find or elicit great character and leadership in his players.
I understand we all get older and lose a step or two, but I think trying to replace Wilfork: not going to happen. Even if we find some guy as big and as fast, it won't be Wilfork and it won't be the Patriots.
