either Chuma Okeke from Auburn or Solomon Hill from Arizona. Okeke was drafted #16 after his sophomore year in 2019. Sat out 2020 due to injury and is playing reserve minutes this year as a rookie. Hill was drafted #23 after his senior year in 2014 and has played significant minutes throughout the last 7 seasons.
2 other players (Ben Bentil and Juwan Morgan) who were late 2nd round or UFA who have made NBA rosters. Bentil only played 3 games. Morgan is deep bench player for Jazz the last 2 years.
Other 6 players on the list went undrafted and didn't make NBA rosters.
To me that says potential is there for possible 1st round pick, but his "most likely" ceiling would be that of late 2nd round or UFA type of player that has been typical for many former BYU star players. It'd be awesome if he could get up to that 1st round status, though.
