I haven't been the biggest Trey fan, but why should he be traded? What relevant information about his basketball and character surfaced in the last 24 hours that we didn't already know? What wrong has he done and who has he harmed? He has the absolute freedom and right to do whatever he wishes in his free time in the privacy of his own home, provided it doesn't harm others or himself. This leakage speaks much more about the character of the person who leaked the pictures, than about Trey to be honest. Unless he engineered that situation on purpose, at most what you can accuse him of is being a bad judge of character and the jump from being a bad judge of character to being a bad basketball player or leader is HUGE! Some of the people with the worst judgement/worst decisions outside the NBA-court have been some of the best basketball players and best leaders of their teams. It's simply a non-sequitur to make that connection.
Now you can have a problem with the morality of what he's done, but that's pretty debatable, as well. For example, I personally don't find what he's done morally objectionable. I find what the person who leaked the pictures has done much worse.
