Maybe I just disagree. RGIII doesn't even tuck and run much. I think there is a misconception about RGIII that says the guy uses his athletic ability to make people miss and is elusive in the pocket.
RGIII is a freak athlete on paper, but the guy is far from Mike Vick or even Terrelle Pryor from a scrambling POV. I think Geno Hayes throws a similar deep ball to RGIII and works pretty similar in terms of athletic ability. If RGIII used his world class speed to scramble out of the pocket and get to the corner more, maybe I would agree. But the truth is, those accomplishments on paper for RGIII just show what type of athlete he is. It doesn't really translate to the field in terms of being a freak in the pocket and using his legs...because he doesn't.
RGIII is a very good pocket passer, and I think Geno Smith is as well. On another note, the gift that is Braxton Miller's feet are his curse. If he could take a page out of RGIII's book and use his arm out of the pocket accurately and consistently, he could be a future first rounder as well.
