Never mind what Michael Bisping says about Luke Rockhold hanging out at pool parties - the party in question was a UFC event, and Bisping is probably bitter that he didn't get to attend (but glad that he got some extra ammo for his twitter war with Rockhold). Luke Rockhold could be a breakout star at middleweight, if he gets a shot at Chris Weidman. He's a former Strikeforce middleweight champion, and he's willing to go before the cameras and say what he thinks - including calling out Bisping for his trash talking, and Vitor Belfort for his past history of performance enhancing drug use. That's exactly the kind of guy you can envision being the face of the division some day. Like every other fighter on this list, he needs to win more than he loses, but you don't have to wait til he's champ to start giving him a push.
