Oh, I think he's going to care. A great deal. Even if he doesn't need a job for the money, he's going to desperately need the visibility of some high profile job where people look up to him.
But I'll be damned if I can guess what it will be, because from what I see, the only people who can put up with him are people who appreciate a well-thrown football. Once he's no longer any good for throwing footballs, I don't know how many people are going to want to be around him on a regular basis.
I don't want to get all Freudian, but I think the guy had a messed up childhood. He's been estranged from his family for 10 years, over issues going back to his childhood. His family was deeply religious, and he was extremely competitive with his younger brother - who apparently encouraged it. That's probably where his competiveness and ths chip on his shoulder came from; he's still obsessed with proving that mom and dad love him best.
