I hate to say this about Vitor

Who beats Vitor?

I think there are several guys at that weight, or who can make that weight who could stop him.
The first one that comes to mind is Kevin Randleman. Nobody short of Erikson has been able to keep Kevin off of them and Vitor wouldn't be the 2nd. Kevin takes him down and punishes him.
Tito *could* do the same, but he'll have to be fast. Tito likes to work the underhook from the clinch, something Couture has success with - but his entrance isn't as polished. Tito also likes to trade in close at times, and that could be a major mistake. Couture was able to work Vitor with uppercuts from in close, while Tito likes to use a bearhug lift - so it's tough to say.
Oddly enough, I think Chuck Liddell might be able to handle him. Chuck is good at fighting off grapplers and is a good striker in his own right. Something tells me he could use this ability to enter on Vitor and actually take him down. If Vitor tries to take Chuck down, there's no way. If Chuck can avoid the big right/straight blast, he'll be okay. Lastly, you'd better believe that his work with Adams could come in very handy if he needs to get a submission win.
Guy Mezger's been on a tear of late. I think he could hang with Vitor. Guy always seemed to not have any power in his strikes, but I think he's finally just broken down and decided to fully commit himself to throwing punches with the intention of ending fights. Guy's also a big middleweight, so he won't get bullied.
On then other hand, I think Vitor would eat Henderson up. Dan's a spraw 'n brawler and is *always* getting hit. Unless he changes his strategy completely - I think Vitor owns him.
Silva is a badass, but I'm not so sure he can beat Vitor. Say what you will about Silva, but he does tend to get hit in the face in most of his fights. Even Sakuraba floored him briefly. Unless he changes his style, I'm not so sure Vitor wouldn't stop him 9 of 10 times.
As for Sakuraba...well, I think the way his fights go, he's a bad match for Vitor, much the way Vitor is for Silva. I see that fight being similar each time.

Some good points.

I also agree that Vitor can handle Henderson, but would struggle with Tito, Sak, and Frank. I also think that Silva has a good chance of winning a rematch with Vitor.

When I watched the UFC Brazil tape I put it on slo-mo to see what Silva did wrong. Basically, he dropped his hands in punching range and looked like he was trying to clinch, probably with the idea of working Vitor over with knees from the inside. Vitor popped him with the left cross, and you know the rest. Something tells me the older, wiser Vanderlei would not do anything that stupid again, and would probably work Vitor over with kicks from the outside before engaging him toe-to-toe. Not that Vitor couldn't win again, but I don't think it would be another cake-walk.

Liddell would be another tough match-up, but I think Vitor's hands would be too fast for him, much like the Yvel fight.

i think if silva and vitor would have rematched the very next day it would have been a totally different fight.
i like chuck lidell, but when he fights he just seems a little slow. i don't mean retarded, but it's like he's cruising along at 55 instead of 90.
