20. Chuck Liddell vs. Tito Ortiz II (UFC 66)
Result: Liddell wins via TKO (punches) in 3:59 of Round 3
Another grudge match, and an old school favorite for those who have been fans of the UFC for a long time. Both fighters are considered legends within the sport, as they brought in a tremendous amount of exposure to the UFC and MMA in general. Considered one of the greatest rivalries in history, the rematch between these two lived up to everything the fans wanted to see.
Liddell was able to secure the victory in the third round, via a brutal ground and pound TKO, asserting himself as the best fighter in the light heavyweight division.
19. Jose Aldo vs. Conor McGregor (UFC 194)
Result: McGregor wins via KO (punch) in :13 of Round 1
While it is tempting to place this higher up the list, it’s tough to get overly hyped over a 13 second beat down. The incredibly quick fight isn’t what makes it so great, rather the events that occurred because of the results. Jose Aldo, a fighter who had been wiping his division clean for years, being knocked out so handily was the upset that shook the world. It gave Conor McGregor, who has done wonders for the sport since, all of the exposure he needed to begin his very quick ascent to international fame. It was also some of the most entertaining pre fight trash talk ever.
