A guy named Lande has ranked top 200 NFL prospects at Sports Illustrated. He has Hunter at no. 36, Patterson at 39, two OL in the 90s, and Bray at...189. He doesn't rank any QBs very highly--it's a weak year for QBs, obviously. Bray should stay and work (hard) on his footwork and pocket presence, mobility and try to develop some leadership skills. If not, he will bust in the NFL--too much like Ainge. It will hard for him regardless, with his lack of mobility and resulting tendency to panic when rushed. He really needs to find a great QB coach and work with him in the off-season--ask his Dad to hire Tedford.
Hunter and Patterson certainly have the potential to be good in the NFL, but IMO it will take each of them at least a couple of years. Hunter needs to get stronger and tougher, while Patterson needs to improve his route-running and become a real wideout and not just a pure athlete playing wideout. Big difference. Receivers have to be smart these days with all the hot reads.
