Shaun Hill is serviceable, but lets be honest... there's no way that he will ever be a top half QB. I do believe in the mantra that you don't pass on a potential franchise QB unless you have one already.
Bradford doesn't have a huge arm, but he takes care of the ball and is very accurate. He's young, but would be able to sit behind Hill for a year or two.
IMO #10 is kind of a sweet spot to take a QB. You can land a very good prospect, but don't have to pay the cap crippling salaries of the very top of the draft.
