I don't think he is done, I believe he just signed a 10 fight contract not to long ago. I do believe he has been bored for a few years now and showboating is how he entertained himself. I love watching him fight and hope to see it again.
He beat himself.
I think he was insulted that the best the UFC could offer him was a guy with 9 fights, and rather than prove his point by just plain ol' beating the crap out of him, no fuss, no muss, he wanted to make it look ridiculous.... and he accomplished that. Success without challenge is often the worse thing that happens to a fighter. What a stupid way to lose. It's weird because I'm glad that he got KTFO'ed for being a clown, but so sad to see the greatest, most dominate run of all time end that way. Hopefully, the next 10 fights we see from him will be back to where we see how much better than everyone Silva is when he does everything right; not how much he can break every rule and get away with it.
I don't understand the interest in a Roy Jones fight. I don't follow MMA but I'm a bit of a boxing fan and RJJ hasn't been relevant for a long time. To say he's past prime is a huge understatement and it's quite sad he's still getting fights.
Even years ago when he fought Calzaghe he was way declined. Why not a B-Hop fight? He's still going strong, breaking records and breaking fighters half his age in the process. I guess if you had to see a RJJ vs Silva fight you could bill it as two hands at their waist fighters who eventually fell to left hooks lol. Jones against Tarver and Silva against Weidman, who'll land the first left hook.
