Georges St-Pierre (GSP) retired on Thursday in Montreal, Quebec, Canada. In my judgement, he’s not merely the best fighter ever in mixed martial arts (MMA) history, but had one of the best-executed professional careers we’ve ever seen. From his debut to ascension to reign to sabbatical to return to retirement, no one has ever done it quite like GSP.
Winning UFC titles in the welterweight and middleweight division in the champ champ era was important, but so is having the most title defenses ever. He’s done both, both accomplishments each of their own era. There were never scandals around his name, no run-ins with anti-doping authorities, nothing. While he butted heads with UFC President Dana White, he always did right by the sport. He is the greatest of all time.
