he hasn't regressed, however he is fighting better boxers on his own weight and that is why he look so $h1tty but he is the same guy that beat up baldomoir, little cotto and small lopez...
True that! If Canelo wants to go toe to toe than he should be gunning for Kirkland (which might happen), GGG and Chavez Jr at a catchweight. Everyone else left at JrMW to fight are not sluggers for the exception of Kirkland.
Don't give too much credit to the subtitles. The translators missed the essence in several spots. Canelo's brother said "Las peleas se ganan tirando putazos" which translates more into the basic "You win fights by throwing punches". He's just saying you have to hit the guy to win the fight.
