If we are getting Lawson that would mean most likely letting Booker go.
We have ~8.29mln in non-guaranteed contracts we can trade.
Trevor Booker $4,775,000
Bryce Cotton $845,059
Jack Cooley $845,059
Elijah Millsap $845,059
Chris Johnson $981,348
Here's our other players under contract:
Gordon Hayward $15,409,570.00
Derrick Favors $11,933,333.00
Dante Exum $3,777,720.00
Alec Burks $9,213,484.00
Trey Burke $2,658,240.00
Rodney Hood $1,348,440.00
Rudy Gobert $1,175,880.00
Grant Jerrett $947,276.00
If we want to get Lawson's $12,404,495 contract, we need to send back at least 8.27mln to Denver. That's the exact # we have in non-guaranteed contracts. If we want to keep Millsap, put Jerret instead of him in the trade. If we want to keep Booker(and not Millsap), we need to include other players. The obvious candidates being Trey and Jerrett, but that won't be enough - we need about 1.1mln more to reach the limit. Hood? I'd really hate the FO if they decided to trade Roscoe in such a trade.
If we want to keep both Millsap and Booker, that would mean trading some of the massive contracts(Burks?).
In general, the most likely victim of such trade would have to be Booker. If I had to guess it would be something like Booker+Burke+Cotton+Cooley+Johnson+Jerrett+Utah's 2015 1st round pick for Lawson.
