There's really nothing to say here.
Tito Ortiz simply dominated Ken Shamrock in all three of their fights, seemingly never showing weakness against "The World's Most Dangerous Man."
In their first fight, Shamrock's corner stopped the bout in the third round, culminating into Ortiz's record-setting fifth-straight title defense at light heavyweight.
In their second fight, Ortiz bashed Shamrock with an arsenal of elbows, ending the veteran after just one minute into Round 1.
In their last fight in 2006, there was much of the same. Ortiz stopped Shamrock early in the first round by way of a TKO victory.
So it's quite clear that this once-heralded rivalry was never really a rivalry. It was more or less Shamrock talking trash and thinking he had what it took to contend with the best, but Ortiz's Octagon presence deemed to difficult to overcome.
Imagine they fought now? Oh, boy.
