Why so much hate on Reggie Bush being overrated?

I do care about the combine very much so. Reggie Bush has only been overrated in one sense. He hasn't been an every down running back that can carry a team on his shoulders in the running game. But he has made up for that in other parts of his game such as recieving the football and in the return game. Overall, he is far from being overrated and as a running back I think he is coming into his own and will be good for awhile to come.
