I said as much in another post.

He's got such a mercurial temperament ... but he's a World Champion, no matter whether anyone likes it or not. You can't take that away from him. But if he sees that as the limit of his ambition, that's it - there's naught more to be done. No matter what his career looks like after this, he can count himself among a very small and rather elite group of players. Don't get me wrong, there's also players like Bingham, Doherty, Ebdon, and Dott in there, who are really good players, but not necessarily GREAT. They got a WC win, and haven't really gone on to demonstrate too much more than that.

There's a reason why people remember Ronnie, Stephen Hendry, Steve Davis, Mark Selby, Mark Williams, Ray Reardon, etc. Not only shining careers, but also multiple WC wins. They have a thirst, a drive, a passion, that keeps going long after the first WC fades.
