I can kind of believe that Mayweather didn't do it on purpose. Pacquiao as great as he was, never learned how to properly cut off the ring through his career.
If there's anybody I would watch Conor fight in boxing, it's Aldo. At least that will be competitive. By the looks of it, Aldo seems better at this point. Here he's sparring Mikey Garcia, not an undersized, out of shape, retired fighter. And he looks decent, granted Mikey is obviously going easy. According to the guys talking in the background, Mikey said Aldo hits as hard as Maidana.
