Every coach in the county misses on kids. Everyone knew going in the staff was taking chance on those players sad thing is it didn't work out. As for the other two who, knows, not every player hit the court ready to go.
Prohm cannot win when it comes to some fans. He gets talented players in and then gets blasted when they leave to get paid. When he brings in players that are going to be 4 year players he gets blasted because they are not ready from day one.
I will say I don't think I've seen too many situations where it's apparent kids aren't Big 12 material before the first exhibition. That is a pretty serious evaluation miss.
As for the "4 year player" thing, I guess I'm still waiting to see a freshman that he brings in that he develops into a serviceable 4 year player. It's been very much feast or famine on high school players.
With that said, I certainly don't fault him for having some kids leave early on him. That's great he's brought in that type of talent.
