What is this resume you speak of? He didn’t nail the coffin at LW, and one defense at WW, whoever it may be, doesn’t put him anywhere near WW GOATs such as GSP, Usman, or Hughes. So if he’s not the GOAT at any specific weight class, how is he a GOAT at all?
Champ champ is it’s own category that should be applauded, but if you ain’t puttin up title defense numbers like MM, Anderson, GSP, Bones, Aldo, etc.; what exactly is your claim to the throne? Champ champ means that you moved up for a (usually) favorable match up and bailed before you could dominate that weight class.
