Georges St-Pierre is by far the greatest MMA fighter we've ever seen.
He cleaned out his division more than once, he clearly and unquestionably defeated the only 2 people to beat him, one of them being a fighter regarded as the greatest welterweight at the time both by stoppage.
He has the most wins in UFC while tied with Cerrone and Bisping, GSPs quality of opponents is far greater than the other two.
He is easily the smartest fighter we've ever seen in MMA. He's the perfect ambassador for the sport.
He retired with the welterweight title the only people that really question the Hendricks win are people that don't like GSP and are best ignored
Between August 2007 and November 2013 there was no question he won all of his fights, from 07 to 11 he didn't even lose a round
He returned after 4 years in a new weight class and took out the champion. Unfortunately health required him to relinquish his title he made no attempts to hold up the division in this period.
He has no drug scandals. he hasn't suffer a series of losses
GSP was above Anderson and Fedor when he retired in 2013 and made it impossible for those two to match him after coming back to defeat Bisping.
Fedor continues fighting and suffering humiliating losses and Anderson Fails drug tests and fails again
Jones who is mentioned and probably should be the greatest can't stay clean for fucking one fight and deserves no consideration. Bury his career.
