There's a lot we still don't know about Conor. We don't know if he has heart, if he has a chin, if he has the stamina to go 5 hard rounds, ect. We know Aldo has all these things. Conor has beaten some solid to decent opposition: Max Holloway and Poirier were solid wins. Nothing close to a Jose Aldo level.

Maybe Conor will step up to the challenge and be great, maybe Aldo has had one too many wars and will get "old" overnight, who knows. I wouldn't put money on Conor though.
