The risk in the INT numbers is that Darnold starts to believe his press clippings combined with slight regression in his OL and WRs ...
I agree with @RaceBannon that Darnold is really good ... but it wouldn't shock me if his numbers weren't quite as good this year
Tells me that he's got skills and is in the process of learning how to use them.
Also experience tells me that you learn the most from the mistakes that you make.
I seem to also remember that being a criticism at times of Josh Rosen while he was in HS as well ... he seemed to do ok as a true frosh this year at UCLA.
I think Darnold is a stud ... my comments saying that he may have a few struggle moments this year has nothing to do with that opinion ... they aren't mutually exclusive.
As for Rosen, the commentary coming out of 2015 was how much better Rosen was than Browning when the numbers really didn't support that fact. We don't know what we'll get out of Rosen this year so until we see a few games we'll see. There's still a very good likelihood though that Rosen will end up being a very good QB.
