As Demetrious Johnson looks to close out another chapter, one of MMA’s greatest fighters reflects on his biggest rivalries. Johnson, the former UFC 125-pound champion and current ONE flyweight champ, has fought Ian McCall, Joseph Benavidez, John Dodson , and Henry Cejudo twice throughout his career. Johnson has now become good friends and training partners with Cejudo, but if he could pick a favorite rivalry, it’s Dodson.
