Vitor's first MMA fight was in 1996, no one is hyping him anymore.
Belfort has always been a tier 2 type fighter. He can beat anyone other than the champions or guys who routinely compete for the championships.
He's knocked out Bisping, Akiyama, Franklin and Wanderlei.
His only losses are against Jones, Couture, Anderson, Henderson, Overeem, Ortiz, Liddell and Sakuraba. If those are the only guys who have ever defeated you, you've had a pretty damn good career.
There's no hype involved with this guy. It's pretty obvious what you're going to get with him. If you have a good enough chin to take him into deep waters, he will wilt and you can impose your will on him. The problem is that most guys can't make it out of the first round and a half without getting knocked out. He's not a guy that's going to use amazing technique to wear you down. He knows what his bread and butter is and that's his one strike KO power. Why work teh jab when you only need to connect a straight right one time?
