Right on vince, this is exactly what the team needs.
Realistically, the kind of atmosphere that the Pats always had in the past come as much from the right attitude in the middle as it did from the leadership. Yeah, you had Rodney and Vrabel enforcing, but that only works if there aren't many guys that need to be enforced. Maybe one or two guys can destroy chemistry, but it takes a whole team to build it.
Ideally, you're looking at a couple of vocal leaders, a bunch of guys who don't need to be led, and then maybe a couple of guys who, without structure, would become malcontents. As long as the Pats continue to fill the middle of the roster with guys like Warren, Mayo, McKenzie, TBC, Chung, etc., who just go out and get the job done, then Wilfork stepping up and asserting himself as the alpha dog could be a great step in the right direction. If those sorts of guys all fall into line with Wilfork, then it might even be possible that someone like AD could be essentially forced into line.
