Are you sure we can cancel their contracts and pay them more this summer? Pretty sure Gobert has to play out his rookie contract, even if he signs an extension. I'm seeing that's the case with Westbrook and Davis. Also appears it was that way with Durant and Rose. I know AD signed a record extension last fall, but he's still earning $7M THIS season. That extension doesn't kick in until next year when he's in year #5 of his career.

I certainly think you pitch them on taking less. Actually, Rudy has the first shot at setting the tone since he can negotiate the terms of an extension next summer. Cap wise, it's better to hold off since his QO would be so low. But face it, Utah doesn't have to reserve space for a LaMarcus Aldridge or hope they can get Bosh like Houston did in making Parsons wait. And it backfired on Houston. If Rudy would agree to 5/$100M, Lindsey should JUMP at that. It would show Hayward that Rudy was leaving money on the table to try to keep everyone together. SOMEONE would certainly offer Gobert a max 4/$100M deal, perhaps even with an opt out clause like Hayward so at 7 years of service he'd be eligible to negotiate a 30% deal. He's so dominant defensively I think a few teams would be willing to give him that amount.
