Dude has been a mauler in the run game and struggled a bit in pass protection, but he has been in no way terrible. The man gave up one sack against the giants, which is solid as hell considering the fact that Justin Tuck or JPP were on him all game. He gave up one sack against the Bengals, again solid when going against Michael Johnson/Carlos Dunlap. He shut down Ryan Kerrigan. And he did a hell of a job against Justin Houston. Sure he's struggled at times, but people have to remember that he's a rookie who just made what, his 6th start? He hasn't even seen everything and sure as hell hasn't gotten his technique down. Like others hae said, his problems arent physical. They're mental issues that come with being a rookie, and are completely coachable. He's going to be a damn good tackle in this league.
