If we really do land Jon Gruden, it's a no brainer: Bray. I'd love to see what he could do under Gruden's tutelage.
Think of what Kiffin did with Crompton and then imagine what someone like Gruden can do with someone as physically gifted as Bray. I have no doubts with the right coaches, Howard, Dallas, Croom and Blanc can do enough to make us not miss Hunter and Patterson with Bray's talent throwing the ball.
I think Worley and Peterman can do great things under the right staff too, but neither of them are as physically talented as Bray is. Bray's problems are all mental and I blame coaches for that.
