Agree that if he stays healthy he could be a factor. But the same problems that Brady had last year are still there. A sub par receiving corps. No one that can separate and burn up a route. Nothing but slot types that run in middle of field.
A friend of mine says that "Cam Newton's head is available", meaning let the defense hit him hard a few times and he gets upset instead of getting mad. If the Patriot's offensive line can protect him, he'll be effective. If they can't then it will be a long season for Cam.
He has a fragile psyche, always has always will. Gets roughed up a little and the frustration starts showing. When things are going good and they're reeling off the yards he's very good. He feeds off of momentum. It will be interesting to see what he's got left in the tank. And how he gets along with Belichek.
