As it stands now, Bradford without a doubt in my mind. Bradford wasn't flawless but he had elite arm talent. His combination of accuracy, touch, and arm strength were the best since Carson Palmer imo. And he was sneaky athletic. On top of that, he was a sound college decision maker with a quick, compact, and effortless release. His upper body mechanics were nearly ideal.
Much more polished player than Mariota and a more accurate passer. But not the physical talent that Mariota is. Still, Bradford was so much further ahead as a passer that Mariota's greater physical talent wouldn't be nearly enough to deter me from drafting Bradford.
What flaws did Bradford have?
1. Obviously, the durability questions
2. Pocket presence as he didn't face much pressure in college but he did look good when he faced it so wasn't an overwhelming concern for me
3. Pocket movement...this was a concern because he didn't have this at Oklahoma due to the blocking and it's essential in the NFL
4. Lower body mechanics...a minor concern that ties in with pocket movement, Bradford was far too static and flat with his feet when sitting in the pocket
