Georges St-Pierre—31 years old
St-Pierre is still on top with an incredibly long reign as the UFC welterweight champion. He has not fought since April of 2011, where he beat Shields in a unanimous decision. It was a similar performance to many recent GSP performances as it left many wanting more.
Knee injury aside, it is getting tougher and tougher for St-Pierre to keep his spot at the top with elite fighters like Condit, Diaz and Kampmann constantly on his heels. Condit poses many problems for GSP with his movement and his length on his feet.
If St-Pierre can win, no matter how he wins, he will once again declare his dominance in his division and as one of the greatest fighters of all time.
Carlos Condit—28 years old
Even though Condit has been making his steady climb, he has not been the most active fighter in the UFC since he arrived in 2009. He has only had four fights and one in 2012 to set up this date with GSP.
Condit defeated Diaz in February and then decided to wait for this title shot with GSP to come, instead of staying active, sharp and defending his interim belt. Considering the amount of activity early in his career, Condit has earned his right to wait, but it doesn't make his interim tag any more legitimate in doing so.
If Condit can win, he will definitely be able to bask in the joy of defeating and dethroning GSP. It is how he does it that will really tell the tale for Condit and show if he is the new sheriff in town, or just a passing tenant to the penthouse of the UFC's toughest division.
