UFC 278 was what fans come to mixed martial arts for. The extremes of the sport delivering on the highest stage just when you think they can't get any wilder.

Leon Edwards earned the welterweight crown just as everyone was ready to once again hand the belt to Kamaru Usman. Edwards was dominated for most of the fight before a head kick in the final minute of the bout landed flush and knocked Usman out cold. The loss snapped a 19-fight win streak for Usman and ended one of the most dominant reigns of the modern era. Edwards extended his own winning streak to 10.

Plus, Paulo Costa and Luke Rockhold battled over 15 grueling minutes before Costa was declared the winner. Rockhold left everything he had in the cage, including smearing his blood in Costa face in the final moments of the fight.
