Seriously. GSP is the GOAT MMA fighter. 10 straight title defences in a WW division that was full of killers. Only lost 2 fights ever, and avenged both with finishes. Beat 2 Hall of famers. Never talked trash. Never got busted for any type of PED. The first half of his career was almost all finishes. Then he blew out his knees, and couldn't get the finish, but still dominated guys like Condit, Diaz, shields, Penn etc. Like serious wtf? In my eyes I'm okay with GSP coming back and fighting Bisping for the belt. GSP retired the WW champion, with more title defences than any WW will be able to try to pass. He wants to move up and challenge for the belt. So be it. He's earned it. Sherdogs hate for GSP makes zero sense.
