Orlando is a mess. They historically don't develop players very well-- guys like Oladipo & Tobias Harris improved dramatically after leaving. They don't draft well, and haven't hit a home run in the draft in over a decade of mostly lottery picks.
The only guy that seems to have actually developed into something is Vucevic, who is a legit all star this year, and now it looks like they're on the fence about keeping him. All of Vucevic's numbers this year are incredible-- traditional stats, advanced stats, +/-, etc... My bet is they don't trade him, and he leaves this summer in free agency as the best under-the-radar non-max contract move for some team.
