Maybe Leonard would be included in this trade, and Withey going the other way? That'd possibly ease the loss of those 1sts..
To add to the plausibility of this trade, you've gotta throw in Neto too, obviously they could use C.J. McCollum as more of a PG in this scenario, but other than that it'd leave them with just Tim '8.8 mpg' Frazier at PG.. and again their whole team is structured for the PG and SG to throw up 3's and the other guys to rebound, which might not be the best way to utilize Favors talents anyway - Their 5th option on offense, of their starters now, is their PF...
A trade like this is interesting though.. I'm all for some sort of 2 for 1 swap.. If I was a GM i'd wouldn't trade those first round picks for anything less than potentially better 1st round picks.
So lets say the Trade was Favors, Exum, Withey, Neto this years 1st round pick unprotected and the 2021 1st round pick, for Meyers Leonard and Lillard (which works in the trade machine)
That leaves the Jazz with this juicy lineup/perimeter rotation(lotta firepower..);
Lillard/Burke/ 10-day contract (Olivier Hanlan?!)
Hood/Burks*/Johnson
Hayward/Ingles/Hood
Lyles/Booker/Leonard/ (Jeff Ayers?!)
Gobert/Leonard/Pleiss
Which is damn malleable moving forward(even without my prized draft picks!).. The Jazz could still designate Rudy for a 5 year contract.. Portland did that with Lillard already, he qualified for the 5 year 30% 'derrick rose rule' max..
Lastly I just want to point out -- trying to gauge Dante Exum's trade value at this point is a dangerous, dangerous game. In a profession where jobs are on the line, and overturn happens quickly.. I wouldn't want anything to do with it..
