Go back to his Freshman year. He feasted on middle to low G5 competition, just not as consistently as he did in 2020. He improved relative to past G5 performance, that's it.
In his career did not fare well against P5...low 60's in completion rate, 1 to 1 TD to Int ratio, 3 pick sixes. Jury's out on his decision making under pressure (was rarely pressured in 2020) and his ability to read defenses. Speed of game could be an issue for him.
I think his performance dropped off with team performance against P5. He could be really good surrounded with NFL talent at WR.
