Trevor Penning

I do not think he was nasty at all, just a dirty player in practice but on game day when players started punching back it showed he did not have the ability to counter.

Could be the davenport of the offensive line.
That is not what was on his college tape or the reports coming during his first camp. He was aggressive, not dirty. He ruffled a lot of feathers in camp for driving the players he was blocking back through the whistle and tossing them around like he did in college. Being that aggressive was what made him a first round pick and the coaching staff throttled that aggression completely and it turned him into just a guy.
