I saw that Colby said he wants to fight Adesanya next if he beats Usman. Personally, I feel it's silly to allow that so there should be some prerequisite to moving weight class to fight another champ. -Minimum three title defenses or one title defense and a win over everyone in the top five in the past five years. -You had to have had one MMA fight at the other weight class before jumping to it. -Nobody in the top three of the other weight class is available to fight for that title.
