This is true, but I was on for Mayfield anyway - I just saw him look too amazing in too many games in college. Crazy accuracy. His size IS an issue, and I didn't think any of the QBs was an across the board lock, but Mayfield was certainly the most impressive on the field and my #1, followed by Allen and Rosen. Darnold never did it for me - too many dumb turnovers and unimpressive throws in big games.
Newton also played on a great team in college. I can't speak for everyone, but I am comfortable saying he's not nearly as good as HE thinks he is.
