That may have been true back then but now that Durant trade fell through interest in other options such as Collins might now be real.
Realistically, options to upgrade PF position:
Julius Randle
Kyle Kuzma
John Collins
Anthony Davis (if he can't stay healthy)
Young PF's on rookie deals are gold to teams so don't see teams lining up to deal.
I'd add Jonathan Isaac as a dark horse. He's on a reasonable contract with protection in case he doesn't return from injury. Orlando has a crowded front court and might look to move Isaac or Carter Jr.
Isaac is only owed $16 million this season if he doesn't play in upwards of 70 games. He's owed $2.6 million if he hits 70+ games. His cap hit is actually $17.4 million
Next season, 2023-24, he's only guaranteed $7.6 million with the same 70+ game incentive for an extra $2.6 million. His full cap hit is $17.4 million, again.
Then in 2024-25 his deal is not guaranteed at all, however same incentives and salary.
He can earn up to $20 million annually but he has to earn it. There's little risk for the team that has him from a financial standpoint. He's a great defender with serious length. We don't need him to be an offensive juggernaut either, whatever he gives would be gravy.
