Williams would walk him down and throw explosive, unorthodox leads and Conn wouldn’t be able move accordingly because he can’t predict the unorthodox trajectories of Williams’ punches.
I think that would work both ways. Conn would move in ways that leave Williams unable to set his feet to punch hard.
Cleveland would rip Billy Conn apart, like actually tear him to pieces, and I’m not even exaggerating. It wouldn’t just be a mismatch, it’d be a full-on “why did they even let this happen?” kind of situation. People would talk about it the way they talk about Ali-Holmes, except even worse , like the kind of fight you don’t rewatch because it’s just uncomfortable and gruesome to wathc like if you were watching something illegal straight out of the deepest pits of the deepweb. Commentators would be begging for the ref to stop it by round two. Honestly, the whole thing would be so one-sided you’d get tired of hearing me say it but no, for real, it would’ve been THAT ugly and maybe even more.
Well Billy Conn did last 13 rounds against a more skilled and dangerous punching heavyweight champion in Joe Louis. Many thought that fight was competitive.
