You would be an idiot to not play a player hoping you get an NBA quality player for another year.
Further, he will likely lose all we if he's not been promised a RS and is that high of quality.
If hes RS as an upperclassman, he will likely transfer if he's that good.
Does this help, or is this a real possibility not just theoretical. Truth- a handful of player leave after their freshman season. Truth 2- that good of a player should never sit your bench, I don't care how good you are.
