i am a biased yates fan and of course i feel he won all 6 of his titles,without question,but i think of all the fellas in the old guard,nasser came the closest to defeating him,flex and kevin were better genetically,and should have pushed him more,and shawn came closest in the back dept. but nasser seemed to have more heart and drive and once he figured things out,dialed it in and pushed dorian more consistently than the rest.
