Up until he got beat by Haye, he did have a good career and I went to watch a few of his fights including the Haye fight. But I don't like this fight. If Enzo is serious about continuing his career, and there's no reason why he shouldn't then he shouldn't fight Jones.
If he wins, it doesn't get him anywhere near a shot at anything, and if he loses, he's finished.
As for RJJ, I have no problem with him carrying on fighting because he loves the sport,( if it was just for the money I would have a problem) but with his form over the last couple of years, I don't think he's worthy of a title shot.
RJJ can fight who he likes. Enzo has been at LHW Recently I believe, if he can do that , I'd like to see him fight Cleverley. That would be fun!
