The greats? Silva and Crocrop both failed drug tests....
Big Nog was the second best fighter in Pride, not a glowing endorsement. Then he went 5-6 in the UFC...
Fedor is a GOAT contender despite a heavily padded record because he had a crazy long win streak, beat two top 5 heavyweights in their prime (Big Nog and Crocrop) and never failed a drug test.
Couture got a decent finish rate because he fought 2-3 weight classes higher than GSP. Pretty interesting that GSP's first finish in years came in his first foray into a heavier weight class.
And despite Randy being one of my favorite fighters, the guy has 8 decision wins... Randy has 30 pro fights over the space of 18 active years with a 19-11 record with 8 decision wins.
GSP has 28 pro fights over the space of 12 years with a 26-2 record with 12 decision wins
GSP has fought in the UFC 22 times and every guy he fought was at least top 10 when he fought them.
Ironically, the only guy on the whole list of guys he faced at 170 that I wouldn't have considered top 10 when he fought him was Matt Serra...
