Tonight, UFC 152 goes down in Toronto, Ontario, Canada, and in the main event, Jon Jones will look to defend his light heavyweight title against another former champion, Vitor "The Phenom" Belfort.
Belfort hasn't fought at light heavyweight in five years, and hasn't fought at light heavyweight in the UFC in seven years. He is a massive underdog coming into the fight, and rightfully so.
Nobody is giving him much of a real chance, even though he will likely have an advantage when it comes to the fans.
However, should Belfort pull out the victory, it will replace Georges St-Pierre vs. Matt Serra as the biggest upset in UFC history.
A win for Belfort would essentially cement his place in the UFC Hall of Fame, as he would be the second ever two-time UFC light heavyweight champion. The only other person to hold the belt twice is Randy Couture, who, ironically, lost the belt to Belfort.
If Belfort wins it will prove he is one of the best of all time, winning a belt eight years after first winning it, and 16 years after making his MMA debut.
With a win, he will upset a champion who is seen by many as unstoppable and on his way to becoming the greatest of all time.
If he wins, he will take the prestige of Jones and gain it all for himself, proving that he was—and is—one of the best of all time. Proving that there was no old Vitor or new Vitor, but that there was only one Vitor, and that he truly is the Phenom.
