#floydmayweather #mayweather #caneloalvarez #canelo This is when mayweather taught a young Canelo Alvarez a boxing lesson. Canelo threw a left hook here to swipe Mayweather's guard away, leaving his face exposed so he can land a right hand. but Mayweather was already ahead of the curve, using his shoulder roll to deflect Canelo's right hand, then came back with a right hand of his own that landed cleanly.
