Hope Grandstaff finds what he's looking for. Two transfers in six months is the sign of someone who is deeply unhappy about something. Based on what was said after he left OSU, I think Grandstaff is struggling with the transition to College and dealing with the fact he isn't automatically the best player on the team. Instead of dealing with the deficiencies he has as a player, he's likely just getting mad at the coaches and projecting his failures on them.
Wish the best for Grandstaff, but glad he left. He would have never been successful here, he's gotta find out what he wants from basketball first. Sometimes you have to get the door slammed in your face many times before you start realizing where the problem really is.
