#4. Former UFC two-division champion Conor McGregor
Conor McGregor has kept all options open for his UFC return. The former two-division champion has been called out by many fighters both at lightweight and welterweight. With plenty of possible opponents to choose from, the thought of a trilogy bout with Nate Diaz could be appealing.
McGregor vs. Diaz is one of the sport's biggest rivalries and their previous bouts set records for the promotion. Their first encounter in March 2016 generated over 1.3 million pay-per-view buys. Diaz submitted the then-featherweight champion in the second round, which set the stage for a rematch.

In August 2016, 'The Notorious' got revenge as he defeated the former TUF winner via majority decision. The rematch was more successful for the promotion as it generated 1.65 million pay-per-view buys. The trilogy could surpass those numbers.
#3. UFC 'BMF' titleholder Jorge Masvidal
Diaz vs. Jorge Masvidal seems like a bout that the UFC could book again. In 2019, the two popular scrappers headlined Madison Square Garden for the 'BMF' title. The promotion created the championship specifically for this bout.
Despite hype leading into the event, the bout wasn't the result that many expected. 'Gamebred' defeated Diaz via doctor's stoppage after the cageside doctor ruled that Diaz was unable to safely continue. The Stockton native was unhappy with the decision as he felt that he could have continued.
Since then, the two have gone in a different direction. Masvidal unsuccessfully challenged Kamaru Usman for the welterweight championship twice before lost to former teammate Colby Covington.
Diaz vs. Masvidal 2 would be lucrative for the former TUF winner to end his current contract on. The rematch could easily headline a pay-per-view.
