6. Ricardo Arona
Arona was not always the most pleasing fighter to watch, but no one can discount the effectiveness of his style. One of the top fighters to ever come out of Brazil, he was a three-time Abu Dhabi Combat Club Submission Wrestling World Championships gold medalist and used his world-class grappling skills to ascend the MMA ladder.
Arona fought only four more times after his defeat to “Shogun” and disappeared from the MMA scene following a unanimous decision victory over Marvin Eastman in September 2009.
