There is no guarantee that Cam will even play when we face the Pats. He's not a QB who is known for studying, first off. The guy is a goof around type who is at his best off-sched, so in the Patriots' system where guys really need to be situational masters and bring a mental edge I seriously doubt he'll win the QB job.
And if he does end up starting look at who he's going to be throwing to. Only good thing for him in that scenario is he should have a stout run game to fall back on, and offensive balance as well.
People are forgetting that the Pats have a fantastic defense. The matchup with them isn't too much about Cam either way even if he ends up with the job. Cam is gonna be Cam.
