I am sure that is the feedback he has been given or something similar. He is a fantastic playmaker and if he can bring that 3 pt shooting into the 35% range, he will be a top 5 pick. He certainly can be a Doncic type of player if he can develop that shot. Doncic is a great outside shooter, so it is no easy task.
I honestly could see him coming back in year 2 and playing another year at BYU and taking his shot to another level in the offseason if draft feedback has him in the late first round. Big difference in that first contract if you are a top 3 pick versus 25th.
