I think this trade is pretty self-explanatory for both teams.

Thunder get a big to play along side Chet which will be helpful in a lot of match ups in the west (wolves, nuggets, lakers,)

Magic get some much needed shooting and a 1st rounder. Magic still have Issac and Wagner, so losing Wendell will not leave a massive hole in their roster.

If anything, maybe the thunder throw in an additional 2nd rounder to this trade.
