It's a bit much bashing somebody for "going off the rails" when they're only engaging in behaviour that's generally socially acceptable. Drink and social drugs are both fine with the majority of people, where is he going off any rails?

His career came to an abrupt end with a shattering KO. At the level he was boxing at, the spectacularity of the KO and the fact that he was basically at the end of his prime and only going downhill from then on meant he retired. And then he behaved exactly like almost every wealthy young guy behaves, well within those parameters actually. Look at how many famous people you hear doing exactly the same sort of stuff and they're just the ones who get caught/don't have PR people to kill the stories in the media.

If he wants to come back to go out on a win then I'm right behind him. If he looks like he's got something left, and I don't think he will have, maybe another shot at a title, but hopefully he beats some journeyman up and goes out on a win.
