2012 was a big year for the welterweight division, with an interim champion being crowned, an undisputed champion returning, and the top ten getting shaken up. 2013 looks to be even bigger with many of the top welterweights already lined up for big matches. Georges St. Pierre has a grudge match against Nick Diaz, Rory MacDonald is getting his rematch with Carlos Condit, Johny Hendricks is putting his title shot on the line against Jake Ellenberger, Matt Brown is looking to continue his streak against Dan Hardy, and former number one contenders Demian Maia and Jon Fitch are facing off.

#10 Demian Maia

Maia was a good fighter at middleweight, and many people think that the only reason he started to lose was he moved away from his roots. Well, his career at 170 so far has shown that when Maia uses his ground game, he can win fast. His submission victory over the always tough Rick Story proved that submissions do not have to put a fighter unconscious to win. Now he gets his biggest test to date at welterweight when he takes on Fitch.
