Sixers get lakers pick next year. It's unprotected. And in 2019 it goes to the Magic.
Unprotected Lakers pick to Philly next year, but since it didn't convey this year, it would have to be 2 years from next year for Magic (Stepien rule). BUT, because of that, the Magic pick becomes 2 #2s instead of the #1 due to a stipulation in the trade about when it could convey. That's why this top 3 was so big for the Lakers, it's a triple whammy: 1) Get a top 3 pick. 2) Convey presumably a worse pick to Sixers next year. 3) Keep the Magic-owed #1.
