No,because conor had the mystique when fought khabib and it collided at the right time. It would be different If conor was still a legit fighter with some recent wins under his belt
Conor is still famous, but he is not viewed as a top fighter anymore. Casuals don't worship him now, so a win wouldn't really elevate Islam that much
Though with the build up sure to be absolute trash from Conor's end? It may elevate him somewhat after he fucking crushes him in a single round
Conor is 36 next year, without a top win in 7 years and recovering from a leg break. He is just a name now, that is all.
