As much as I hope Bray is already as good as you seem to think... what exactly are you basing these comments on? Stephens has elite arm strength. He has a year in the system. He has both real and mop up PT in the SEC which NO camp or HS competition can come close to simulating.
Between the two, Stephens will have the stronger arm. Stephens is physically stronger by a wide margin due to 3+ years in a college S&C program. Stephens is heavier and only 2" shorter. Bray has good feet compared to HS Sr's... not compared to a guy who has been playing under SEC caliber coaches for 3 years. Bray may be more accurate but that tends to diminish as defenders get faster.
I just don't see how you can claim he will "easily be twice as physically talented" as Stephens. If Bray is good enough as a true Fr to beat out a RS Sr with SEC caliber talent then we'll all be thrilled... but count me among the those who'll wait for the real proof.
