I know many on here are very critical of Whitworth though he is one of the best tackles in the NFL (though he is a better pass blocker than a run blocker). Anyways here are some of the numbers from profootballfocus.com

The Blind-Siders
While you can look at Dahl’s 200 pass blocks and think the sample size skews the data, you can’t say the same thing about the men that follow him. Joe Thomas is widely regarded as the finest tackle of his generation and finishes second, just ahead of Andrew Whitworth who gave up one less pressure, but was in pass protection at tackle for 72 fewer snaps. Neither man covered themselves in glory in the run game, but a franchise left tackle first and foremost should keep their quarterback upright, and you can’t deny that either man excelled in that regard.
