UFC welterweight champion Kamaru Usman weighed in on who he considers the greatest MMA fighters of all time.

Usman, who is ranked No. 1 pound for pound by USA TODAY Sports / MMA Junkiethe fighter sat down with ESPN and named four fighters who make his cut – one in his weight class.

Usman will continue to try to secure his own legacy by picking up his sixth title defense on Saturday when he takes on Leon Edwards in the UFC 278 main event at Vivint Arena in Salt Lake City. The main card airs on pay-per-view after preliminaries on ABC/ESPN and early prelims on ESPN+.

Check out Usman’s roster below, which he picked based on his skill and technique.

Anderson Silva has defended his UFC middleweight title 10 times, second only to Demetrious Johnson for most title defenses in UFC history. “The Spider” thrilled fans with iconic knockouts, and his 16-0 start in the octagon is the best in promotion history. Usman can tie that record if he overtakes Edwards at UFC 278.

Jon Jones

Other than a disqualification for an illegal elbow in a fight he was dominating, Jon Jones has never lost in his career. Jones ruled the UFC light heavyweight division for a decade, but troubles outside of the octagon forced him to have his title stripped several times. He defended his title eight times during his first reign and three times during his second before vacating his belt in August 2020. “Bones” is looking to continue his greatness by moving up to heavyweight, but has yet to makes his debut in the division.

Georges St-Pierre

Georges St-Pierre is widely regarded as the greatest welterweight of all time. Usman is chasing the Canadian Hall of Fame and was once dubbed the No. 1 170-pounder of all time by UFC President Dana White.

St-Pierre defended his welterweight title nine times before deciding to retire in 2013. He returned after a four-year absence to dethrone then-middleweight champion Michael Bisping at UFC 217 and join a select few to hold titles in two weight classes.

Dominique Cruz

Dominique Cruz

Perhaps no champion has faced more adversity than Dominick Cruz. Enduring an injury-plagued career, Cruz was instrumental in building the bantamweight division. He was forced to vacate his UFC bantamweight belt after just two title defenses due to recurring injuries, which forced him out of fighting for nearly three years.

His comeback in 2014 was flawless when he ran through Takeya Mizugaki at UFC 178. Then, in perhaps his biggest career moment, Cruz came back from another injury to dethrone TJ Dillashaw in 2016, taking over the title he never lost. However, his reign would end at the hands of Cody Garbrandt later that year, and Cruz has seen mixed results since.
