I can't even imagine Carson Palmer doing anything like that. Think about it - does CP ever run for a 3 yard first down in the first quarter when down 7-0 and jump up and pose like Superman for the cameras? Newton is a 100% self important entitled douche. This year he became a good player too, which means we have to suffer this idiot every week. I hope beyond hope we wipe that smile off his face next week.
Their fanbase is talking about last years playoff game. Fools. This year we're not starting our 4th string QB for the game.
Carson was fined for thrusting his body at the stands. So, to answer your question, I could see him doing it.
