Easy to say from where I sit, but I'd seriously be contemplating retirement if I were him. I know he's still owed tens of millions, but he's likely also made enough at this point for him, his children, and perhaps even their children to live a comfortable life. Why continue to subject himself to this indignity? I know it would be more a case of quitting than retiring, but even walking away is still a better look than this.
I'm guessing that a guy who held out, to squeeze a couple extra million into his contract, isn't going to walk away from that guaranteed money. To all us John Q Public guys, we see the money, and arrive at your conclusion, that the next couple generations of his family are already financially set. But to the wealthy, there's nothing wrong with having a lot more money. And I'm sure that he believes he can turn this thing around. When someone has the success he's had, the last thing they lose, is the belief that they can return to their former greatness. When they lose that, that's when they walk off the stage.
