After reading a bunch of these back and forth threads on who the best of all time is, I'm not sure if everyone is viewing this through the right lens. P4P: irrelevant, but if you need an excuse to make miniature and undersized people relevant, then DJ is probably the most logical bet. GOAT: This is what matters. The only criteria is if 2 people walked into a cage, who is walking out? For ex. Bones vs GSP. I have to imagine Bones is walking out. Another example: Fedor vs Mighty Mouse... Fedor is walking out of that cage. Weight classes, how good of a run someone had, etc. are great talking points for a fighter's fans, but the baddest mofo is the GOAT. It doesn't matter if the are fortunate to have more size, strength, reach, etc.
