I have a hard time believing Trey's character. Not in an off the floor sense, but moreso "I'm going to do whatever it takes".
He played very selfishly all year. Whenever he got out there he was more concerned with what he was doing then what the team was doing. Opportunity was served on a silver platter for him, but he squandered it and became one of the worst players in the entire league. He was barely average in a few areas, and terrible everywhere else.
Trey's got to get it out of his head that he's going to be a star. It's not impossible for him to be the player that he wants to be, but he needs to be the player the team needs first. He doesn't have the baseline ability to be an NBA player right now.
