If you remove the key defensive pieces and #1/2's, you're left with:
Luol Deng (who may end up making less than $10mm next season, and is clearly overpaid)
Danilo Galinari (who is arguably a #2, and can actually create offense)
Eric Gordon (overpaid; can create offense and shoot better than Gordo)
Tyreke (see above)
Nic Batum (meh)
Rudy Gay (ridiculously overpaid)
Nene (a legitimate starting big)
Not a lot of great comps. Most of the other players you've listed who might get $10mm+ per year on their next contracts can create offense better than Gordo or fill a key defensive role. With players who can competently handle/create and defend, the added value of Gordo's play-making and defense is pretty minimal. You'd probably gain more signing a mid-level or less spot-up shooter than you'd lose from Gordo, before factoring in cost. Gordo seems to be stuck in no-man's land: Not a good enough lead and without the right skills to fill a complementary role.
