He's definitely "ahead" of anybody on the roster in his knowledge of Grubbs/Doboer's system. And if you watch his HS coach break down their system he may be ahead of some of the guys on our roster who's shown a real weakness for understanding how to read a defense.
And, a few have made comments about his height. A tall QB has a distinct advantage in some obvious ways, but chiefly his release point is significantly higher and his vision is greatly improved.
Obviously, short QBs can manage (like Bryce) but taller QBs have an advantage, for sure. I think it was Brady's brain that made him what he was, but standing at 6'4" or so didn't hurt either.
