UFC 258: Usman vs. Burns odds, predictions: MMA insider shares surprising fight card picks

Kamaru Usman says he isn't worried about whether he will go down as the greatest UFC welterweight of all-time. The champion says that distinction is for others to decide, while all he can control is his performance in the Octagon. Usman will make the third defense of his title on Saturday against Gilbert Burns in the main event of UFC 258. The main UFC 258 fight card is set for 10 p.m. ET. Usman won the belt from former champion Tyron Woodley in dominating fashion and also has made two defenses look like relatively easy work.
