I think it will prove to be a fad, RG111 is already injured and not likey to be able to plant his throwing foot equally well upon his return. Teams will start to go after Kaepernick and Wilson and try to damage their legs ASAP. How long will their careers last, not very long I think?
The NFL fact has always been, run your QB at your own risk, it is quite another to put your QB at risk quite a bit in a game and I just don't see them surviving very long. A couple of crippling injuries, and nobody will want to try it again.
And proud of it!!!
