I agree, Usman and Khabib will always beat Conor, but I think Conor is a far better athlete than Masvidal, and could easily defeat him. He's faster than Masvidal, better than Masvidal, more athletic than Masvidal, and hits twice as hard as Masvidal.
I also think Conor could knock out Tony Ferguson in a brutal one or two round knockout. Ferguson gets dropped a lot by guys with nowhere near the striking game of Conor. I also believe Conor would absolutely annihilate the slow, ponderous, Justin Gaethje, probably in one round.
With Ferguson, Conor either knocks him out around one or two, very possible, or gets eaten up by him after round three.
