Does Reggie Bush have a Learning Disability ?

[nunusguy]

Apparently he had one incredible game yesterday in Miami based on 170 + yards of rushing on 26 carriers including a long TD run of 60 some yards. I'm told that he was looking like the guy who when coming out of USC in 2006 was supposed to be the next great back to enter the NFL ? Well he's been anything but that until yesterday, but this is his 7th year in the league. Has the learning curve to
be an effective NFL running back been that steep for Bush ?
