During his UFC 212 podcast, Rogan says McGregor is the best UFC featherweight of all time.
I’ve got say Conor [McGregor] is the greatest 145-pounder of all time cause he knocked out Aldo, who was clearly the greatest. But in terms of who’s got more victories of course it’s Aldo. The problem is — we’re not doing MMA math here — you’re having two guys actually fight each other. So if you said who is the greatest of all time? Well it would have to be Aldo because he beat all these guys — no, no no, because the two of them fought and Conor merked him. So you’ve to give it to him. Otherwise there’s no other metric. There’s no other metric other than a knockout…He’s the best ever. You have to say he’s the best ever even if he never fights featherweight again. Why? Because he KO’d the best ever. The reality is Aldo’s the best ever but Conor KO’d him. You couldn’t say without the Aldo fight that Conor was the best ever. But once they actually fight, that’s it. That’s all that matters. It’s not MMA math. So you’ve got to give it to him.
