Leak may be in consideration because he's playing for a high profile team and he is a good QB. If UF wins out (or one loss) and he's in good shape. A key loss or a couple will knock him out.
That said, I think he and Ainge are about equal in talent. Russell and Cox are pretty much in the same area. All good but none great.
Quinn isn't out yet. Playing for ND, the preseason hype, Weiss and some big numbers to come will put him right back in it. (which sucks!)
