We don't know if Bush is ready to be one of those 25 rushes a game back in the NFL. And those are the only questions surrounding him, but it is still one to be considered greatly when drafting.
Bush is obviously the more talented player coming out of college but we're looking at this trade value wise. Teams are going to dish out more picks and money for a player coming out of college like Eli, who has the pedigree and the numbers to back it up instead of a RB, even Bush.
