He’s 0-3 in the last few years, just turned 38 and has been sitting out half retired contently & loudly chirping from the sidelines for much of that.
While in that time Buckley has been fighting and still in that competitive fire. Has won 6 fights in the same stretch Kamaru has fought three times
Usmans old, knees shot and from the looks of it checked out of fighting, he could have retired the last couple years and everyone would have been fine with it. But dude is coming back into a hard time at the top of WW where the game has passed him by.
