In Boxing, the "best pound for pound fighter in the world" is unquestionably Floyd Mayweather Jr.  In the UFC, that distinction may just belong to the popular Canadian welterweight Georges St. Pierre.
 
The 26-year-old St. Pierre was at his absolute best last night as he dominated the 34-year-old Matt Hughes in their rubber match, scoring a second-round submission and winning  the interim 170-pound Welterweight Championship that was created especially for this match when champion Matt Serra pulled out of the scheduled match with Hughes due to a severe back injury. The 15-2 St. Pierre even outwrestled Hughes, who is known for his outstanding grappling ability.
 
"I think Georges St. Pierre has the potential to be the greatest 170-pounder ever," stated trainer Greg Jackson. "He's just phenomenal. The scary thing is he keeps getting better."
 
With UFC planning to run The Bell Centre in St. Pierre's hometown of Montreal on April 19, UFC President Dana White will do everything he can to score the Undisputed Welterweight Title Match between GSP and Serra. White was almost giddy in discussing the possibilities, stating "It's insane how big this sport is in Canada, and especially how many Canadians come down here, whether Georges St. Pierre is fighting or not. The sport is so big in Canada, it's mind-boggling to me."
 
Hughes, a bonafide UFC legend, tried fighting as a southpaw, which was  wrestling strategy he said his camp had initially devised to combat Serra's right hand. But it clearly didn't work against GSP, whose domination of Hughes was nothing short of shocking. GSP closed the bout by taking Hughes down with a judo throw and then slapping on an armbar. Hughes had no choice, and submitted verbally by yelling the word "TAP"  at 4:54 into Round 2.

In October, 2004, Hughes submitted St. Pierre at UFC 50 to win the vacant championship. GSP became the champion by beating Hughes November, 2006 at UFC 65. But an ill-prepared GSP lost the title to in his first title defense at UFC 69 to Serra.

Hughes, who grew to dislike Serra when they were rival coaches on "The Ultimate Fighter" cable series, happily gave his prediction of what would happen when GSP meets Serra again. Nursing his battered and bruised face from the fight that took place just hours before, Hughes stated "Matt Serra's going to go down that ladder just as quick as he happened to pop up that ladder."
