Thank you for looking at this using your football brain, instead of just parroting what the headline and top level stat says.  The DP needs to employ real football analysts instead of just reporters.  

Bolles did well.  His mistakes really weren't half of these penalties.  I saw a couple of plays where the attacker got him turning and was able to get to the play going on behind the line of scrimmage. Those are the ones I hope they work with him on.  Other than that, I think he's gonna be a very good LT.
