There are probably some unique things about Utah's team that are inflating his stats in some way (similar to KC's triple-double record).
Saying Delon is a generational college talent doesn't pass the eye test. He wasn't first team all american. He didn't win conference player of the year. He didn't play very well in the tourney and his team still went to the sweet 16. His draft stock is dropping to where he's no longer assured of being a first round pick.
