Listen to the Cam Newton interview after the game, right out of the horses mouth he says that was not the only big hit.
Don't try to tell me what I seen and didn't see, I've watched Newton all season, even the coaches knew there was a problem with Newton throughout most of the game.
Tell me this Einstein, how is the hit that almost knocked Cam out(the one you're talking about) and didn't come anywhere near his back cause a severe back injury? It didn't, the one I'm talking about that caught Newton square in the middle of the lower back did the most damage.
