The Carolina Panthers lost for only the second time this season when they were defeated by the Denver Broncos 24-10 at Super Bowl 50 on Sunday, February 7.

At the post-game press conference Carolina quarterback Cam Newton was in no mood to talk. Visibly angry, the 2015 NFL MVP, fielded several questions before abruptly getting up and walking off.

NFL Network analyst and former player, Deion Sanders, was critical of Newton's behavior.

"You are the face of our brand right now, you can't do that," Deion Sanders said after the game. "I understand the emotions of losing, but you can't do that. A Manning, a Brady ... all these guys who are a prototypical type of quarterback in our game, they're not going to do that ever. Would Drew Brees ever? You're opening yourself for more criticism," he said. "Because everybody is going to say you're dabbing and smiling and smiling and styling. So this is how you go out when you lose?"

CBS Sports' Boomer Esiason wondered if Newton has mental issues.

"I'm not a psychologist, but I almost feel like he's Bipolar," Esiason said. "When things are going great he's on top of the world. And then when things go bad he basically sulks. It's like one extreme to the other. There's no real balance there. There's no stability there. There's no consistency there."
