Joshua is the kind of guy who could have made it in about 6 different sports if coaches had gotten him at around 15.
Surprisingly, former Featherweight champ, Jorge Paez. A former acrobat in his family's circus, he could walk on his hands and stand on his head for long periods, do back flips and was exceptionally agile. He sort of changed styles midway during his championship run from an aggressive brawler to a versatile boxer/puncher with good footwork and mobility.
