Dunno if I agree about that Adesanya hasn't ducked anyone, he's faced all the top contenders and won including a credentialed wrestler in Yoel. Usman's had one serious challenge in Colby, hopefully Burns provides another otherwise he might end up in a similar scenario to Adesanya having cleared the division, the difference is I don't think Usman moves up. I think Whittaker would destroy Usman, given the current depth in the LHW ranks Adesanya definitely has the potential to not only win the belt but hold it for a while as well.
