LAS VEGAS — In the last 15 months, Amanda Nunes, who was widely acclaimed as the greatest women’s mixed martial artist ever, lost her championship. On Saturday in the co-main event of UFC 285 at T-Mobile Arena, Valentina Shevchenko, who is clearly the greatest flyweight of all time, was submitted and lost her championship to Alexa Grasso.
In August, Kamaru Usman, who was the No. 1 pound-for-pound fighter in the world, was knocked out in the waning seconds of his fight and lost his welterweight title.
