Well, one thing is sure. If you have ANYTHING even slightly negative to say about Bush you're going to get thumbs down from everyone.
My thoughts - he'd be a beloved fan favorite if he'd been an undrafted FA. Even then, he's only a 3rd down back and punt returner. If he can protect the ball he'll be a nice asset down the back stretch. We'll need everyone to contribute this year and his time will come along with Lance. Having the burden off his shoulders should keep him healthy.
