I dunno, Peyton walking off the field without doing the handshakes with the other team? Kinda poor sportsmanship and out of character for Peyton. If it really was his last game would that be how he wants to end things? <Edit: I just remembered he did the same thing when the Colts lost to the Saints in the Superbowl. Guess it's not out of character>
Personally I really enjoyed the game. I'm a Seahawks fan and watching them walk all over the favored Broncos was a treat
Especially the times there was a big play for the Seahawks defense.
