Cam Newton is the unquestioned best player on an undefeated team with great numbers and there are still folks looking for ways to give other guys the MVP.
I know a lot of people are just shitting on Cam but here's my thoughts, between the big four so far: Palmer, Brady, Wilson, Cam.
Palmer has been playing lights out football, and some of his throws last night were unreal. However, the Cardinals are a team that is stacked top to bottom with talent, so I think even with Drew Stanton, they would find some success and make the playoffs as a WC, so I'll cut Palmer.
Brady has been dealing with an average defense and Oline, a revolving door of RBs, and injuries up and down his WR core. However, as long as he has Gronk he puts up good numbers. Without him, Brady looked mortal. I know the injuries, but compare this to the next two.
The Panthers have no one really on their WR core, but Greg Olsen is making plays, albeit not to the level Gronk is. Add in the fact that Cam himself is moving the ball on the ground even when his receivers can't do anything, and that puts him above Brady for me.
The Seahawks are in a similar position as the Panthers, with a mobile QB, strong defense, and no name receivers. However, the reason I may side with Wilson is that he doesn't have Marshawn Lynch. Jonathan Stewart isn't on Lynch's level, but he's at least better than Bryce Brown and Christine Michael. I know that Stewart is hurt now, but Wilson had to literally will his team into their current streak, without their star running back. So that might just edge out Cam for me. Either one are excellent choices though
