First, if Dedmon is willing to take his offer (he won't be), why not have him also opt out and re-sign for the RE? May as well optimize if we're going to talk about best-case scenarios.
Second, the tax system doesn't work that way. You pay for where you play, not where you're based. So it ends up being a much smaller difference than you assume.
Third, are you accounting for Bertans', Forbes', Murray's and Simmons' deals ing with the new CBA? The team would have about $3 Million less in that scenario. And yes, their contract would be adjusted upward to match the new min.
This is about what your scenario would look like:
| Name |
2017-18 |
| LaMarcus Aldridge |
$21,461,010 |
| Kawhi Leonard |
$18,868,625 |
| Dewane Dedmon |
$3,000,000 |
| Tony Parker |
$15,453,126 |
| Danny Green |
$10,000,000 |
| Tim Duncan (stretched) |
$1,881,250 |
| Kyle Anderson |
$2,151,704 |
| Livio Jean-Charles (waived) |
$414,080 |
| Dejounte Murray |
$1,357,874 |
| Jonathan Simmons |
$1,522,119 |
| Bryn Forbes |
$1,357,874 |
| Davis Bertans |
$1,357,874 |
| Roster Charge |
$843,740 |
| Roster Charge |
$843,740 |
|
|
|
|
| Total |
$80,513,015 |
So we're talking like $21.5 Million in cap space
