UFC 306 at the Sphere in Las Vegas is going to be one of the most remembered Ultimate Fighting Championship events in recent memory. However, that has little to do with what took place in the cage, despite the best efforts of Esteban Ribovics and Daniel Zellhuber. Given how the co-main event between Valentina Shevchenko and Alexa Grasso sucked all the energy out of the arena, the headliner between Merab Dvalishvili and Sean O’Malley would have had to have been a “Fight of the Year” contender for the crowd to feel fulfilled by the action.
