Georges St-Pierre is the most dominant welterweight to ever compete inside the Octagon. He usurped this distinction from Matt Hughes after decisively finishing the former champ on two separate occasions.
St-Pierre's current welterweight title reign has spanned almost five years. In that time, he's chalked up win-after-win with veritable ease. GSP has rolled through every opponent, utilizing his superior wrestling to grind out unanimous-decision victories.
St-Pierre also holds the record for most significant strikes landed (1153), highest takedown accuracy (75 percent) and is tied with Hughes for most UFC wins (18).
Even more impressive is St-Pierre's performance against Nick Diaz at UFC 158. GSP was still getting back to 100 percent after ACL surgery, but this fight showed that he was still the best at 170. He completed nine takedowns and worked over Diaz for five rounds, landing a total of 210 strikes.
St-Pierre is the most beloved athlete in the Great White North, and that's saying something, given Canadians' love affair with all things hockey. He was even recognized as the Rogers Sportsnet Canadian Athlete of the Year in 2008, 2009 and 2010.
GSP single-handedly helped to make Canada one of the most desirable (and profitable) places for the UFC to put on events. According to the UFC's website, "UFC 129: St-Pierre vs. Shields at Rogers Centre [in Toronto]...obliterated almost every UFC record including attendance (55,724) and gate ($12.075 million)." The card also pulled in 800,000 pay-per-view buys.
St-Pierre is also responsible for the outpouring of Canadian talent flooding into the UFC, which includes welterweight contender Rory MacDonald.
