As for the vid. I know Ohio state has a QB stigma but I have a hard time believing that would hinder teams from choosing Fields. The scheme they ran with Fields was completely different than what came before and he started with the arrival of a new offensive minded HC. I suppose GMs may have discounted some scout reports due to history but that's being ridiculous.
It's actually worse than not taking Mahomes early because of Texas Tech's O. No, I'm not comparing them as players. Fields is less projection because you could actually watch him run pro concepts in college. I can see some of the concern about navigating a pocket and staying home too much but that's easily corrected with fewer WR options on routes and more reads related to presnap. This O has more early recognition concepts that should allow peeking at the rush. That he would like to more mimic Wilson tells me that he's aware of this as well and will work more on keeping plays alive.
Unlike RG3, he will slide on runs and really tries (too) hard to not break the pocket but he has an even greater ability to extend plays than he's shown in college. If that becomes more common, he could become elite.
It's rare for me to say that because mobile college QB tend to need to be told to stay home and I don't think you can get sustained NFL success without being able to throw from a pocket but we already know he can do that.
