re: P manning always seems to say the right things in interviews

In the interview he says that they had some issues in protection.. We all know that the QB has a lot to do with identifying the D to the rest of the team and calling out the protection, just pre-snap.. and after the snap, Peyton has to identify the the blitzing backer and throw hot if need be.. All of which is associated with "protection"... So although it may sound like he was throwing his OL under the bus.. he was probably stating that they had trouble as a cohesive unit with the protection.
As far as him yelling at his lineman like that.. Its called being a leader and taking charge of his offensive unit.
