Quote from the article above
But not everyone within the organization agrees on Williams. He didn't play hard at the beginning of last season, nor was he consistently productive. Casserly and Kubiak study all his games; they don't believe any of these negatives is persuasive enough. They also have questions about Bush. If he is this good, why did he play just part-time at USC? And why, near the end of the national championship game, did USC turn to LenDale White more than Bush? Do you pay No. 1 money to a guy who will not be a full-time back? They never answer these questions to their satisfaction.
This is what I have been saying all along about Bush. He is a great prospect coming form college, but do you pay #1 money to a Part-time RB.
