Anyone who says Bray is more talented than Stephens at this point is talking out of their ear. I hope Bray is great but he will take development before being a SEC starter.
Neither guy will scare SEC DC's running the ball. Stephens has a stronger arm by far and did as a recruit as well. Bray looks more accurate but you have to consider the competition.
I really, really have no bias on this. I will be giddy if Bray comes in and takes the job. But there is NO CREDIBLE basis to say the kid is more talented than Stephens until he plays against similar competition and shows it.
