The Colby Usman fight was one of the best title fights in recent times IMO. Was expecting a dull enough grappling match, but they just stood and traded the entire fight. Was very close until the KO. He definitely deserves a rematch most out of all of Usman's opponents.
That being said, I think the Masvidal fight was one of the biggest selling non McGregor PPVs, so can see why Dana would be interested in that one. They have the excuse that Masvidal didn't he a full camp, I suppose, but would a second fight really do huge numbers after how the first one played out?
