Not trying to accelerate the debate, but who says Barrett cannot win a game by himself? I suppose if you're referring to simply taking off running, then sure. However, in my opinion, 3 games into his collegiate career, J.T. is as good at getting the ball to receivers in short and mid-range passes and better at his progressions than Miller. I just think you're jumping the gun on pro vs. college level talent. If you're suggesting that Braxton is on par with the names you mentioned above, from a passing standpoint, then I'd strongly disagree. Like I said, give it the year and then revisit.
Not saying J.T. > Miller... just that it won't be as easy as you say.
