2. Michael Bisping
Michael Bisping had and continues to have a great career with the UFC. Bisping won Ultimate Fighter 3, coached by Tito Ortiz and Ken Shamrock, beating Kristian Rothaermel and Ross Pointon before knockout out Josh Haynes in the light heavyweight final for Team Ortiz. Bisping was 10-0 with all finishes before joining the TUF house and would eventually move down to middleweight. Since joining the UFC in 2006, Bisping wouldn't receive a title shot until 10 years later while on a three-fight win streak after going 18-7.
Bisping knocked out Luke Rockhold at UFC 199 to become the first British UFC champion, would defend his title once and then lose two straight, opting to retire in 2017 after his fight with Kelvin Gastelum to due his ongoing eye injury. In 2019, Bisping was inducted into the UFC Hall of Fame and continues to work for the UFC as a commentator/analyst.
1. Kamaru Usman
Kamaru Usman, the best Ultimate Fighter winner and one of the best welterweights of all time, won TUF 21: American Top Team vs. Blackzilians, the only season to feature competing gyms and their respected fighters. Usman is a freestyle wrestler, an NCAA Division II national champion, an All-American, and was 5-1 with all knockouts before appearing on TUF, beating Michael Graves and Steve Carl before submitting Hayder Hassan to win the welterweight final.
Usman would go on an incredible 15-fight win streak, winning the title from Tyron Woodley and defending it five times against Colby Covington twice, Jorge Masvidal twice, and Gilbert Burns. At UFC 278, Usman faced Leon Edwards in a rematch seven years in the making. Usman was well on his way to winning before getting flatlined with a head kick with under a minute left in a fight and subsequently lost the rubber match seven months later at UFC 286. Usman was the former #1 pound-for-pound fighter in the world and will no doubt find his way back in the title picture before all is said and done.
