You and Fanny continue to try my patience. Again... you're not backing up your statements. Ali threw a lot of punches off his back foot, without any leverage. They were punches... just not meant to create damage. He was a master boxer... he knew when to put his body behind his punches and when to punch defensively. Calzaghe, as can be clearly seen in slow-motion replays of his later fights... threw punches awkwardly, not just landing with the wrong part of the glove... but his whole arm motion looks funny. Maybe he was protecting his brittle hands. But it still makes for ugly looking professional boxing.
