Reigning UFC welterweight champion Kamaru Usman has been dominating opponents ever since his UFC debut. Usman (16-1 MMA, 11-0 UFC) took part in Season 21 of “The Ultimate Fighter,” where he represented his former gym The Blackzilians. He won two fights in the house, leading to his selection for the finale showdown with American Top Team’s Hayder Hassan. Usman proved to be the right choice, as he was able to shut down Hassan’s power early, using his strong wrestling to control the fight. After outmuscling Hassan in the clinch, Usman dragged the fight to the mat, as he outgrappled his man in Round 1
