The leverage thing is interesting here.
I do not think Hayward owes the Cs anything but I also do not think there is animosity there. It just didn’t work out and I can understand him wanting to move on for multiple reasons (fresh start, going home, family reasons). I think he told Cs what he wants and they are trying to accommodate. That being said, his free agency options have dried up a little and only the Knicks really have the cap space at the moment to really give him a deal (if they choose to do so).
Hayward wants Indy. I think Indy wants Hayward and they must have had prior conversations about a potential deal for 4 years/$100 mil otherwise Hayward would not have opted out. So I do believe there is definitely mutual interest there.
I do think Indy has some pressure on them as well with Oladipo’s pending free agency looming. I don’t get the sense they are trying to blow it up and rebuild. If they strike out on getting Hayward on a long term deal and Oladipo bolts, they are a lottery team after this season. Think they have as much incentive to get Hayward deal completed as the Cs do tbh.
