If I'm not mistaken, Wilson is at three-year starter at BYU and played well all three years, including as a true freshman. And I don't think the level of competition is much of a concern because (1) he wasn't exactly surrounded by a bunch or 4 and 5-star guys himself, and (2) BYU at least played a decent Division 1 schedule and they weren't just destroying teams with their superior personnel, like Clemson, Alabama and to some extent, Ohio State. Mahomes and Josh Allen certainly didn't play against awesome competition, either.
And while Trevor Lawrence played at a high level for three years, I'd be a little concerned about the evaluation because Clemson was just so far superior to most of the teams they've played the past three years, although I definitely think he will be a good NFL QB.
I agree with you about Fields; I would not take him in the first round.
