You're suggesting, indirectly, that McGregory's magic should be related to important stuff like winning fights against the majority of top opponents his size, defending the belt, not tapping at the drop of a hat, etc. But that is missing the true key to his greatness. McGregory hit a few featherweights (who didn't take him seriously) with a solid left, talked up the wins like he was the second coming of Christ, all the while dragging fans along like rats behind the Pied Piper. That should be enough to cement his status as GOAT, the likes of which no fighting art has ever seen, or ever will see, again.
