Can Newton is talented and I'll bet hungry.
The twin issues for him will be the same as his entire career; game to game (sometimes play to play) consistency, and discipline. I imagine Bellicheck will want to see him mostly as a drop back, play action passer. However, in the end, Bellicheck will use him however he must use him to get wins. If could be different game to game.
Bellicheck has the chops like perhaps no other Coach in the NFL. He wouldn't be afraid to bench Cam if Cam didn't totally submit to what he wanted when he wanted it. Cam knows that.
I think Cam will be a good QB under Bellicheck. Darn it.
