The problem with Peyton blaming the line this year was that he brought it up. He came to the podium and said he knew what the press was going to ask and then talked about protection problems. While he was probably right the press would ask about that with him bringing it up that made it kind of nasty. Much better for team chemistry to actually wait for the press to ask those questions.
You didnt see the whole press conference, before he said that they asked him about it like 20 times and he changed the subject, then he said "we had protection problems", take it for what you want, him not pointing out the correct protection, the line not doing their job, him not getting rid the ball in .1 seconds, or the running backs not picking up their blocks. If you watched the game and say they didnt have protection problems you werent watching to closely. Pit had 5 sacks, and who know how many hurries.
