Sounds kind of silly, but I have mixed feelings about THJ and the draft scenario. If he is rated really high, it will encourage him to leave (obviously), since he probably isn't going to improve his stock much by coming back for a year. In the other sense, if he is undervalued by draft boards, it may encourage him to come back a year, improve his game and thus improve his stock. My concern with the latter is him trying too hard to be a hero on next year's team, and his motivation turning from helping the team to helping his draft stock. I know nothing about his personality or attitude toward the situation, so I am not assuming he will behave this way, I just hope if he comes back, it's because his top concerns are winning, graduating and college experience, and not because he is simply trying to look better for draft scouts, not that I would blame him for the latter.
Coaches' timeouts are worse. Basketball teams should get one, full stop.
