As I recall, he started off his title reign as more of a conventional standup boxer/slickster and then gradually transitioned to a rough and ugly infighter. I'd say his best boxing performance was probably his title winner vs. Lastra.
I don't mind. Just one where he primarily fights on the back-foot, and looks good. He has such long limbs and I'm struggling to think of a performance where he used them in the best manner.
