I think it was Monday's McD presser where he was visibly angry about the O, but more so about protecting the QB. While he mentioned the O-line, I think he was really pissed about play calls that put Allen in Jeopardy. You want to ruin a young QB, let him get hit and hit and hit until he becomes too frightened to stand in the pocket, as we've seen before.
I expect the playcalling going forward will be much more conservative in that respect...
