Fields has the problem a lot of high school stars have--he is a duel threat QB with immense talent, but the passing part of the "duel" is not good enough to beat out a guy like Fromm at an elite program.
Being a great athlete who is a pretty good passer works fine in high school, but not at an elite college program as Trevor Knight learned.
Knight was a highly recruited duel threat starter at Oklahoma who had a good regular season, then destroyed Alabama in a bowl game, when a walk on named Baker Mayfield arrived and walked on at OU. Everyone thought he must be crazy. Knight was four inches taller, faster, stronger, bigger, a better athlete, had a stronger arm, and already the starter.
Mayfield was far more accurate and could process information a fraction of a second faster and he didn't waste a second worrying about having to compete for playing time. He took over the first game and Knight transferred.
The fact Fields couldn't take the competition and couldn't admit there was a reason he got beat out tells me all I need to know why Oklahoma told him they weren't interested.
Fields is obviously a great athlete, but Oklahoma wants guys who like to compete. Kyler Murray sat on the pine for two years at OU, competed his ass off, and when he didn't start just worked harder.
I understand why Fields transferred, but will he compete when things go against him? He hasn't shown it so far.
