If Canelo does so little each round wouldnt someone have run through him by now? Called him out on his low activity? He's fought a littany of top fighters and none of them ran through him. Floyd outboxed him, Bivol outboxed and outworked him, and GGG slightly outworked him in their 1st fight. Yet Canelo beat GGG twice, Jacobs, Callum Smith, Plant, BJS, Mosley, Cotto, Lara, Trout, Kovalev, Kirkland, and Angulo...but you say "Canelo "does little every round". If youre beating that group of guys...youre doing more right than not.
Canelo has elite composure, never overreacts, and uses elite defense and counterpunching to limit opponents output while landing flashier punches.
