Of course he is Angry! He loses perfection and a fourth superbowl ring, Is Injured and misses an entire season... where realistically both of these happen with minutes of each other just looking at game time..
Sees his entire team dismantled and watches his friends retire.
watches his team struggle for the entire 2009 season in the areas of leadership, playing on the road, finishing games.. all areas of where this team made its mark in the past... and he loses the first round of the playoffs where he had probably one of his worst games statistically..
on top of ALL of this... he is now forced to negotiate a contract at probably the lowest point of his career.. even though he still considered the best or one of the best.. its still on him..
I think he is handling it with class. And he is handling it the way he feels it needs to be handled.. A young team with loads of potential needs leadership... I think he's trying to take on even more leadership to help guide them too.. which may account for a lot of his oubursts..
