That's how I feel about the whole thing. I really don't care how cocky one player might be or even arrogant on how good they are. If you cannot back it up after talking yourself up, you should at least be able to get through an entire post game interview asking what went wrong. No doubt he was pissed.
He has a hell of a year, but that doesn't matter when it is the Super Bowl where Carolina melted. A lot of that was on him too as the offense was completely centric on his play. Throughout the end of the game you could literally see him having very immature tantrums either on the field or sideline. That tells me while he cares a great deal and wants to win and has passion, he doesn't have a good handle on his emotions. I don't get to see many Carolina games with my market, but for this year at least he wasn't used to losing. So I am not sure if these kinds of outbursts are typical for him. He did seek out Peyton at the end of the game, and was a sign of sportsmanship, so it's not completely bad, but he has some things outside of his amazing skill to work on next year.
