Master every boxer pretty much has craved attention over the years. Why should Floyd be any different? On top of that he is recently retired and is really missing the action. I think he has enough left that he can beat Canelo in a decision even at 160. He would embarrass Canelo because he is too fast for Canelo. Canelo throws short punches. Mayweather will always be moving laterally and back. Canelo will not land any punches at all. The only way Canelo lands punches is if somebody stands right in front of him like Triple G did
