GOAT is a tough thing to classify. When everyone was calling for Fedor to be named the greatest, he had really only fought for Pride. Even though he was past his prime, his American MMA showings quickly ended any GOAT discussion. The thing with Hendo is that he’s fought for pretty much every major organization… so even with losses to known fighters, it’s tough to argue that he didn’t fight the best in any given era. In my opinion, Hendo is already the greatest currently active MMA fighter and a win over Jones (although I don’t think it’s gonna happen) would solidify that notion. You could argue for Anderson Silva to be in the same category too. Other than those two, I really don’t feel there are many other GOAT contenders.
