Really? You use one of the most commonly known fixed fight in MMA history as a exemple of Kimo's greatness?
Um.... no.
I own a copy of this event, and contrary to what some others have said, this was not a pro wrestling event or match, but a Shootboxing event, (Shootboxing S-Cup 96 to be exact).
To put in perspective it would be like saying k1 had a fixed mma fight on one of their cards. (Shootboxing is/was a legitimate organization founded by kickboxer Ceaser Takahashi).
As for the fight itself... Kimo outweighed Sakaraba by a significant margin, had been training with Joe Morriera for a while by that point, and this was also Sakaraba's first full shoot.
If you watch the fight you can see Kimo land several hard headbutts, not to mention the fact that he completely dominated this fight, which would not have been the case had it simply been a stiff work, like much of the Rings matches in those days.
(A work would have had more of a logic, or back and forth flow to the fight.)
Obviously, Sakaraba was a better fighter than kimo, but every fighter is going to have some bad matchups, and prime roided out kimo, was simply too much for a rookie Sakaraba.
Remember, an almost untrained Kimo devestated Royce Gracie, it's not crazy to see that a much more experienced Kimo would be dangerous to a up and coming shoot-style pro wrestler.
