Cam Newton opened himself up to a firestorm of criticism Sunday for sulking his way through his press conference, then making an early exit. Among those who panned Newton's sour conduct in the presser was Deion Sanders, who said on NFL Network: "I understand the emotions of losing, but you can't do that."

Newton, the league's MVP this season, lost two fumbles that led to touchdowns for Denver in Super Bowl 50. He was also sacked six times and intercepted once in the 24-10 loss. But his postgame performance was even worse:

Contrast that display to the classy way that Russell Wilson and Peyton Manning, the past two losing quarterbacks in the Super Bowl, handled themselves. Wilson threw the game-sealing interception last year at the 1-yard line against the Patriots in the Super Bowl. Then he said, "Put the blame on me."
