Good luck to them adding to their championship drive with that mentality.
Like most fans, you are overvaluing high draft picks that aren't #1 or maybe #2 in the right year.
This trade idea has a ton of wiggle room and can easily be adjusted by giving them expirings like Thabo, Favors, Jerebko, or Udoh. For example, Burks, Favors, Udoh and Thabo for Shumper, Smith and Frye. That would easily bolster Cleveland immediately and hurt the Jazz, thus increasing their own lottery odds. But it's way too lopsided and wastes most trade assets while taking on liabilities.
I'm not doing anything beyond going with the information provided by those more in the know than I am. Now these analysts could certainly be wrong but how would I know?
