The Lakers did not make the move for the late first round pick. They basically just searched
for a deal to dump the terrible Mozgov contract to go for the big free agents next summer.
I could imagine further seeing another deal like this with Deng to make even more space.

Here are both contracts to see again how awful they are:

         2016/17    2017/18     2018/19     2019/20

Luol Deng $18,000,000 $17,190,000 $18,000,000 $18,810,000

Timofey Mozgov $16,000,000 $15,280,000 $16,000,000 $16,720,000
