At 152? Alvarez get exhausted and possibly even stopped. They literally had to carry him into the IV room after weigh-in for the Floyd fight. He cant even make 154 well. At 156? Alvarez pummels him. People too often conflate weigh-in weights with healthy weights in terms of effectiveness. Because 4 pounds for a hydrated, healthy guy makes almost zero difference in terms of anything. But when you are already dehydrated at X pounds, say 155 - squeezing off an extra 3 pounds that your body absolutely does not want to lose makes a HUGE difference. At 152 Alvarez gets stopped, because he just cannot safely make the weight.
Alvarez wins by knockout. Style makes fights. What this fight does show is that if Alvarez was more aggressive against Floyd he would win.
Keyboard warriors that never had to make weight saying 152 lb canelo would be healthy and well fed maidana. Mornons. Canelo would not last 3 rounds.
