What RGIII did at Baylor simply won't work at the NFL level and I said this when he was drafted. His thing was putting a defense in..."will he run or pass". Take that aspect of it out of the equation and he is not all that as "just" a passer. If you watch his Baylor highlights he's tossing the ball around, he's not zipping it into tight widows.
Now add the fact he's immature and pretty much a kid. He has no clue how to act as an NFL player either.
By 2016 he'll either be out of football or sitting on a bench somewhere.
