Money. Jay's income drops off once he retires. He's set financially, but it's hard to say goodbye to the easy pay days. Look at Bill Parcells thinking about coming back and coaching the Saints. Even he is lured by money.
I can't agree. He may be like Parcells, but if that is the case, then that would be about attention, not money.
Yeah, his income drops off to be sure, but he doesn't have to eat as much, and the cost for all those drugs goes away.
Drop some size. It's fake from the juice anyway. Get healthy. Enjoy the rest of your life.
Does he own a gym? Has he been smart with his money? Someone would hire him to write (or pseudo-write) for one of the mags. Personal training could be an option for extra bucks and something to do.
