5. Strikeforce Nashville brawl
Yep, the Diaz brothers are here again. Coming in at number five is the notorious clash at the Strikeforce Nashville show in 2010 between Jason ‘Mayhem’ Miller and the entire Cesar Gracie Jiu Jitsu crew.
Shields had just dominated UFC legend Dan Henderson to defend the Strikeforce middleweight championship, and Miller hopped the cage to confront Shields about getting the next title shot.
Nick Diaz obviously felt insulted, obviously the same stunt he pulled on KJ Noons had fallen out of his memory bank, and he launched a riot-starting right hand at ‘Mayhem’.
The brawl will go down as one of the most infamous moments in sports history, it also killed CBS in terms of major MMA coverage.
