Actually, there were two plays like that.  About the only drawback to Bolles is if you have a guy who can run past the QB and around the tackle to get at the QB, Bolles will fall behind.  He's not slow...he's a tackle, and keeping up with a fast edge rusher most tackles can't do.  As he matures, he'll learn how to jam that edge rusher 75% of the time.

I watched Bolles' play closely for the first half of that game.  The guy is a beast.  Unfortunately, he gets blamed for things that aren't his fault.  The commentator said the run was unsuccessful going to Bolles' side because one play got stopped at the LOS.  If you watch, Bolles actually was doing his job, and it was Janovich who failed to pick up the rush coming around the edge.  Not sure what Janovich was thinking...he ran to the right around Bolles and to the second level.  Not big on that Jano guy.  Anyway, Bolles does his job 99% of the time.  More than one can ask of a LT.
