I'm not suggesting that I think Davis should walk away from the money, but imagine being 33 years old, having more money than 99.9% of people in the world, and sticking with a job you are no longer capable of doing well that keeps you away from your wife and young kids most of the year - just for more money. He must be convinced that he is going to get better or that they will cut him and pay him. What else could be going through his head?
