Usman makes his opponents look lighter since he is jacked. Colby looks like he could go a bit lighter probably comfy at 165, maybe stretch to 160. Colby could do 155 but would be scrawny look like a distance runner. Colby gave Usman as good a challenge as anyone for quite some time. No need for Colby to drop. Usman probably retires before long. LW tough division too so he would just be drained.
