I can't find anything in the legalese that differentiates a player who clears amnesty from a player who clears waivers. But if the double dipping scenario is true, then Roger has the leverage.
https://www.cbafaq.com/salarycap.htm#Q64 describes how set-off works for players who are simply waived -- namely, 1/2 of the difference between new salary and that player's minimum. in roger's case, that's likely to be 0-300K.
around the middle of
https://www.cbafaq.com/salarycap.htm#Q67 you'll see how amnesty set-off amounts are different IF the player is bid on during amnesty -- namely, that the original team gets to subtract the amount of the bid (at least the min salary), any bonuses, and any non-guaranteed salary from what they still owed the player. in roger's case, that would have resulted in at least 1.5M savings.
in the same question, you see how there are no set-offs at all if someone is amnestied and then clears amnesty waivers.
so basically, the jazz had a chance of saving either $0 or some amount north of 1.5M if they had amnestied him. roger and his agent convinced the jazz to not cash in on that opportunity, which tells me the original buyout had to allow the jazz a chance to recuperate some of the possible 1.5M. why else would the jazz not just tell him tough luck and amnesty him in hopes of saving all that cash?
Assuming that is true, he did want to avoid the amnesty process and worked a 'deal' with KOC to do so. Presumably that deal wasn't as simple as being able to negotiate freely with other teams while under contract. Because there was risk (not in hindsight, of course) that he could be claimed in amnesty which would be a horror scenario for Roger.
exactly. for roger, the benefit of saying "just buy me out" is having the freedom to dictate his own future (sort of -- he could still be claimed off waivers, but that's less likely at the full salary). but for it to be worth the jazz, there had to be a financial windfall that was close to what they could have gotten by amnestying him.
So KOC had some leverage. There should have at least been some talk about what the buyout would be if the Jazz let him shop and he didn't get his deal.
HAD some leverage, yeah. and that's probably when the verbal agreement was reached. but now that KOC has lost the leverage of the amnesty threat, bell renegs on the verbal agreement and can suddenly play hardball because KOC has no fall-back option. at least that's my read on the situation, i clearly have no inside info. but it sounds an awful lot like roger pulled a fast one after initially agreeing to something that made sense for the jazz to not exercise their amnesty right.
