Even outspoken Cam backer Brandon Marshall cringed over Newton's post-SB disaster

The sports world can't stop talking about Cam Newton and his moody, pouty, petulant post-Super Bowl press conference -- in which he eventually exited prematurely.

While the few (usually Carolina Panthers blue-lensed) defenders of the league MVP may be citing how it could be unfair to be too hard on a player after losing the biggest game of his life, the resounding chorus of NFL players past and present coming down on Cam is alarming.

Add to the list a player who has had plenty of emotional outbursts, suspensions and drama both on and off the field -- New York Jets wide receiver (and former Denver Bronco) Brandon Marshall.

The 10-year NFL veteran has been outspoken about his own issues throughout his career, overcoming alcohol-influenced legal issues and domestic disputes. Marshall also was last heard defending Cam Newton, though not his dancing, during Super Bowl week on Showtime's "Inside the NFL" over the Panthers QB's love for what some deem excessive celebration at times.

But on the season finale that aired Wednesday night, the six-time Pro Bowl receiver admitted that Newton's act after losing 24-10 to the Broncos Sunday was cringeworthy.

Marshall is not alone in ripping Newton. And we're not even talking about the apparent lack of effort trying to recover his fourth-quarter fumble with Super Bowl 50 on the line that he later defended, or the gold "MVP" cleats that debuted during pregame. But Marshall's take is extremely telling how the culture inside the NFL is thinking about how Newton mishandled himself after the game, not just the Twitter haters.
