Love and Westbrook are good friends... best friends, as far as I understand it.
OKC might be a better environment for him...
Option 1 (minimum changes):
If George is willing to opt-in, a straight up trade would be perfect... nuff said.
Option 2 (Get a legit rim protector):
If he wants to get his $30M right now though, then if James were willing to take a one-year $10M paycut, Cavs could do the following:
Love+Korver(for salary reasons) for George+OKC's first via S&T;
Thompson+Hill+Smith+BKN for Kemba+Howard+MKG/Williams;
Cavs give Hood his qualifying offer
Cavs do not bring back Calderon or Jeff Green, and don't use MLE.
Cavs sign LeBron to a 1+1 @ $25M.
Kemba/George/James/Williams/Howard or Kemba/MKG/James/Howard
With a bench of Hood, Nance, Cedi, Zizic...
Option 3 (Everybody gets paid):
If James wants his max, and George wants his max you could still do it:
Love+Clarkson for George+OKC's first via S&T (Cavs -$6.3M)
Thompson+Smith+BKN for Kemba+Willams/MKG+Bacon/Hernangomez (Cavs -$5.5 avg)
Cavs QO to Rodney Hood
Cavs could max both LeBron and George in this instance; would field:
LeBron: $35.5M
George: $30.3M
Hill: $19M (ugh)
Walker: $12M
MKG/Williams: (avg $13.25M, pick one)
Korver: $7.5M
Osman: $2.8M
Hood: $3.6M QO
Zizc: $2M
Nance: $2M
----------------
~$92.5M before LeBron (-1 roster slot of $550k)
Leaves us $36.5M (-0.5M) below the apron...
James could take all of that money, or, he could leave $10M on the table for the Cavs to use the full MLE and the BAE.
Option 4 (End the Tax):
To modify the the above trade, instead of MKG/Williams just make it MKG+Williams, add in "Juylan Stone" from the Hornets to make salaries work, and that brings the Cavs even further down in salary while replacing the corpse of George Hill.
So the Hornets trade would actually be:
Hill+Thompson+Smith+BKN (3 Players / $51M) for
Kemba+MKG+Williams+ Stone+Bacon (5 Players, $41.5M)
Obviously Stone and Bacon get cut, so it's effectively a swap of 3 players from each team, so roster slots shouldn't be an issue.
Not sure if I prefer this or Howard, and salary wise Kemba+Howard is equal to Kemba+MKG+Williams; but this does make for a versatile lineup...
At the end of a trade like this, with James fully maxed out, the Cavs would actually be significantly below the tax line (by ~$6.5M)....
James, George, Walker, Williams, MKG, Osman, Hood, Zizic, Nance, + 3 roster slots.
Not world-beaters, but, a fieldable team nonetheless. Perhaps one that could create a defensive identity?
