Vince Wilfork didn't sound like a man in much pain.

On Wednesday his name popped up on the injury report for the first time this season when he was listed as a full participant in practice despite a foot injury. When asked about his health on Thursday he shook with laughter.

"I'm fine" he said.

There have been moments through this season's first three weeks however when Wilfork hasn't looked like his normally-dominant self.

Wilfork played well in Week 1 but watched the Bills rush for 136 yards the most by any New England opponent this season. Against the Jets in Week 2 Wilfork was at times held in check single-handedly by guard Vladimir Ducasse.

Wilfork appeared to do a better job of getting off blocks and clogging things up for Bucs running back Doug Martin in Week 3 (Martin's longest rush of the day was just 11 yards) but according to Pro Football Focus after three games and 89 pass rushes Wilfork has just two hurries the lowest pass-rush productivity of all qualifying defensive tackles.

"You always wanna get better" Wilfork said. "I'm always trying to get better. That's the name of the game. I really don't try to [say] . . . 'I've been playing good. I've been playing bad.' It's just one of those things you gotta keep plugging away. There's some good plays I've had and some bad plays I've had. That's football. Everybody goes through that. There's a lot of football left to play so I'm not worried. I'm positive I will play better. I'm positive I'm gonna have some more screwed up plays. Trust me. But that's football."

Wilfork said he hasn't yet noticed much of a trend in terms of the types of plays he wishes he would have handled better so far this season. That sort of self-scouting comes during the bye week when he has time to go back and look at film of himself rather than an upcoming opponent.
