How is Canelo not too big? The dude struggles to make 154 and probably can't make it anymore without being severely drained. Manny never fought above 150 and that was a stretch at the tail end of his prime. He can still make 140 fairly easily, whereas Floyd was a titlist at 154 when he fought Canelo. A better question is, why was that Floyd's FIRST unification bout in his career? If that doesn't sound like a cherry-pickers resume than I don't know what does.
