vucevic is averaging 28 minuts a game and his minutes are not on the decline even though he is not starting. I don't think he has a ton of value, and Butler is worth more than what the Magic are giving up. I just don't know why the Magic would be making moves that give up picks. The Magic should be looking to fire sale themselves. They may think they are close and want to move picks, I just don't know why they would. That trade would put the Magic where the Bulls are now. Maybe the Magic think 500 ball is a good decision. I can see some teams doing it for ticket sales.
Smart is stuck behind a better player, but why would the Celtics want to move pieces for a one shot deal like Wade. The Celtics would probably know they want to make moves that help them for 3 seasons or so. They have to know they probably won't win it this season, but a 3 season window helps them buy time to possibly find another player or allow for the Warriors or Cavs to take a step back (injuries/age). If I am the Celtics I would rather move those players for a long term contract. The Celtics won't have enough with tihis trade to offer a max deal and if they keep wade they will have no cap space at all.
Lastly, lottery pick that is more than likely 9+ is not all that great.
