Ya, I doubt he can rebound from this. I just don't see him being able to repair what he has ****ed up. I really don't know if he will even be able to perform on the course anymore. I mean, he was usually the type of guy that could put everything else aside and have a focus just on his game. This may be too much.
I don't know why in the world this would destroy his golf game or make him unable to perform on the course. Its really not that big of a deal. Hell half of marriages end in divorce. There are literally thousands of athletes out there with much much greater personal tragedies who go on with their lives and continue to perform athletically. In the grand scheme of things, there are a whole lot worse things that happen to many people than getting caught cheating and getting divorced.
So he loses a bunch of money, but he still has more than any of us could imagine. Now he can chase women around openly and party just like he has been. I doubt he will be too broken up over losing his wife, considering he has been chasing every skirt he sees for years.
