current BYU players are NBA material. Not one. 1/3 of NBA material is foreign, which means that approximately 40 of the 60 draft choices are Americans. If you think that BYU has one of the 40 best players in the country, then you are not watching enough college basketball.
NBA material is on another level athletically. Future NBA players stand out athletically from all of the rest. It really isn't much of a question. Many of them are identified before they even reach high school level. That is why if you have to ask, then the answer is "No."
