4. Rory MacDonald
Heir to the Canadian (MMA) throne and possible serial killer Rory MacDonald has been making big statements as of late. At only 23 years of age he's already dismantled UFC legend BJ Penn and ran through mostly every opponent with the exception of Carlos Condit, whom he's set to face in a rematch on the same night his teammate will defend his belt against Diaz. Condit who edged a controversial decision over Nick Diaz in order to fight for the belt is coming off a decision loss to the champ, but he had his moments stunning the world and certainly GSP with a beautifully set up head kick which you can see
here In their first fight a 21 year old Rory won the first two rounds but lost in the third to the more experienced Condit who was able to pull off a TKO victory with some strong ground and pound in the last seconds of the fight. If he was to win a rematch he would arguably be next for the title. But with his teammate as champion his options as limited, as they have both said they would not fight each other he's forced to wait around or go up in weight. If however Georges was to lose Rory would then have a chance to get together with his teammate and decide what to do. In case Georges decides to venture into other things and leave welterweight to Rory then we would get to see one of the most exciting (although not very charismatic) young prospects take a shot at the belt.
