Cam Newton's postgame pity party was uncomfortable to watch. The last place the Panthers quarterback wanted to be after suffering the biggest loss of his football-playing life was in front of a horde of media.
And the last thing he wanted to hear was a Broncos player within earshot describe the Panthers' demise. Newton forced out one non-answer after another, reluctantly expounded just a bit while still saying nothing of import, then reached his limit when he overheard Denver cornerback Chris Harris talking to his own contingent of media just feet away about how the Broncos got to Newton.
This doesn't excuse Newton's behavior throughout the session, but it does bring clarity to his breaking point — the moment he stood up and walked away after having heard enough.
