The case for Demetrious Johnson
'Mighty Mouse' is arguably the most technically complete fighter of all time, a flyweight who mastered every phase without a defining weakness. As the inaugural UFC flyweight champion he set the record for most consecutive title defenses with 11, a run of dominance from 2013 to 2018 in which he blended world-class striking, wrestling and submissions into a seamless whole. His suplex directly into an armbar against Ray Borg at UFC 216 in 2017 is one of the most spectacular finishes in history. Because he competed in the sport's lightest and least-promoted division, his brilliance was often underappreciated relative to bigger names. Traded to ONE Championship in 2018, he won that promotion's flyweight grand prix and title and delivered a flying-knee knockout of Adriano Moraes in 2022. He retired around 25-4-1, revered by peers as a fighter's fighter and a technician without equal.
The case for Kamaru Usman
'The Nigerian Nightmare' built one of the most dominant welterweight reigns in history on a base of relentless, high-level wrestling that evolved into genuine knockout power. He put together a 15-fight UFC winning streak — among the longest ever — and won the welterweight title from Tyron Woodley at UFC 235 in 2019, then defended it five times. He beat Colby Covington twice in grueling wars, avenged an early loss to Jorge Masvidal with a highlight-reel knockout, and outpointed Gilbert Burns and Leon Edwards. His reign ended dramatically when Edwards landed a head kick with under a minute left in their UFC 278 rematch in 2022, erasing a fight Usman was winning. He sits around 20-4, a wrestler who became a finisher and headlined the sport's African golden age alongside Israel Adesanya and Francis Ngannou.
