this is stupid, with good coaches and a good head on his shoulder, he absolutely had the talent to be up for the Heisman.
That's debatable. I think you're confusing a strong arm with overall talent. Bray sometimes put up gaudy numbers in an offense that passed a lot, and rarely by choice.
He only had offers from UT and a couple of mid-majors coming out of high school, and three years of college resulted in an undrafted free agent deal. If he is so incredibly talented, it's amazing that so many people whose jobs revolve around identifying talent keep passing on him.
I'm not saying Bray is going to be amazing in the NFL, but there have been plenty of players that have either gone undrafted or were drafted very late in the draft that turned out to be some of the best players in the NFL. Examples: Tom Brady and Arian Foster.
