That was his leverage. I am sure we would have jettisoned him to another team but BKLYN thinks he will exercise the third year so they offered more. Ideally he leaves early and they suck. As his biggest fan, I hate the way he left but it is reality. He may opt out and sign another huge deal if things don't go well with Kyrie and them. I know, IDDDDIOT
If they fail to win the title, there is no way he takes the PO. He'll opt for one more huge contract for. It's a common consensus that Harden's game will last until he's well into his late 30s. Kyrie is seriously a head case, the chances of that team blowing up because of him is just so high.
