This is what makes these fantasy matchups fun to speculate on. I’m the same way that we have the Arona example for Fedor, we have the Tibau example for Khabib: a dude who was a state wrestling champ in Brazil, and Khabib couldn’t take him down for shit. He was left having to strike with Tibau, and his hands looked pretty bad. That said, I do think Khabib’s hands improved over time.
Fedor-Arona is hard to judge because of the ruleset, and because both were early in their MMA careers. Some ppl say Fedor would’ve lost that fight under unified (or PRIDE) rules, but really it would’ve just been a completely different fight altogether I think. It’s interesting to note that in those two examples, Fedor still won his fight as did Khabib.
We’ve never seen Fedor totally shut down by a smothering grappler (with Bigfoot being the possible exception, and Fedor also defended a TD from him in rd 1) nor have we seen Khabib lose at all, which makes it a tough fight to pick P4P. But since I think Fedornis probably a good enough grappler to neutralize that threat for the most part, and he is light years better than Khabib standing, I have to lean Fedor to win.
