I can understand why a team wouldn't want to deal with that type of project.
The next one I will watch full game of is probably Whitehead... I'm very intrigued by him. And I will try to pick an early game before he got injured.
I'm just reading tea leaves, but I think the thing that's turning people off on GG was his penchant for taking tough (bad) shots instead of passing the ball this year. I think that was situational at South Carolina and can be corrected with coaching. If you look at his Team USA tape, he was a very different player. Someone will see through it and draft him.
Right now, the main thing for GG is his interviews and whether he acts like a professional. He needs to show he's coachable. Guys like Hassan Whiteside and Louis King dropped in the draft because they just didn't come off as serious people during the interview process.
