Heavyweight champion Cain Velasquez seems unbeatable right now. He absolutely dominated Junior dos Santos in their rematch for the title and I can't see him moving from the top spot anytime soon.

Way back in 2006 a young Velasquez made his professional MMA debut in Strikeforce against Jesse Fujarczyk. 'The Ronin' was 3-1 in MMA at the time of meeting Velasquez who, at the time, was a relative unknown.

Velasquez has only been to the judges scorecards twice in his career and all of his other victories have came by KO/TKO, including a one round savaging of his next opponent Antonio Silva.
