Something I was thinking of was...
LMA & Wes, and 2 second rounders
for
#1, #19, Thompson, & Waiters(continued)
After getting Cleveland to agree to that we look to add a 3rd trading partner to offload Waiters because while I'm not high on him he does have value as a young prospect.
Offer Charlotte
Waiters, #19, and maybe Meyers if that what it takes
for
#4
So outgoing LMA, Wes, 2nd rounders (and maybe Meyers)
and
Incoming #1, #4, Thompson
From Cleveland's perspective they get their coveted player and swap Waiters for Wes, who would work better with Irving off the ball than Waiters, and they still maintain enough flexability to offer Lebron or whomever a max or near max contract next summer.
Charlotte trades back while filling their hole at SG and maybe acquiring another high upside prospect, and it's a scoring SG that would work nicely with MKG being less of an offensive threat on the wing.
Benefits for POR are opening up massive cap room this year and next, plus adding a bunch of young talent to the roster to try and kickstart a fast rebuild from a roster that could be stuck in mediocrity with LMA looking like he's on the way out if that's the case. Personally I target Len and Oladipo with the 1 and 4, and use the 10 on someone who can score and hopefully create a bit of their own offense like McCollom, with KCP and Shabazz as possibilities.
