Wooga will workout really well because he can shoot and is super athletic and this will get him drafted late first or early second. I actually think he will be a solid role player in the NBA, provided he can spot up shoot and not actually be asked to handle the ball too much (which is his main weakness). If a guy like Quentin Grimes for the Knicks can get major PT, I don't see why Wooga wouldn't. It would also be better for Wooga to go after this year, because I actually think the more he is asked to do, the more his stock will drop (since he isn't well-equipped to be the focal point for a team) so he isn't someone that would benefit from another year.
The only other player on the roster with NBA potential is George and I think he would absolutely benefit from coming back another year. The issue with him is although he is a freshman he just turned 20 which means he is the age of a typical sophomore, so I am worried he gets rushed into the NBA.
