His resume and streak is on par with Jones, Anderson, Fedor. Yes GSP has less losses and blemishes on his career than those 3. However, GSP isn't regarded like MJ, Gretzky, Tiger of MMA because he left doubt in peoples mind. Could Woodley have beat him? How about Khabib? Before anyone says b-b-b-ut he's not prime GSP, GOATs take risks. GSP wasn't some slow old man, he even said in his retirement speech "takes a lot of discipline to leave at the top". Yes he's at the top but there is viable opposition available. With someone like MJ for example, it's pretty much unanimous across Bball that if given equal teams, no one is getting past MJ in the finals. Lebron's close and in many eyes is more talented but most NBA viewers agree MJ is more accomplished still. GSP is in GOAT convo, but not clear cut GOAT.
