Objectively, Usman >> Khabib in all-time rankings.

[B-Man]

OP's post will be deemed controversial but when you look at it objectively Khabib isn't even a lock for greatest lightweight ever, he needed another couple of title wins. I have Usman ahead of Khabib at this point.

Khabib mauled his opponents, Usman fought to a draw tonight.

BJ Penn was never P4P No.1 and was never undefeated, so its not even close.

Usman is comparable since he become P4P No.1,

GSP too never become P4P No.1 he is too behind Khabib and Usman.

I'm saying Khabib has 3 title defenses.
He had less fights in the UFC than Jones had title defense.

He was awesome but there are levels here and Khabib simply didnt stick around long enough to be classified w the greats.
