His output was much higher than usual. He broke his significant strike landed record and it was a 3 round fight, so he almost doubled the output. Max stopped him twice in the third round after Aldo started to fade in both fights. Cardio was definitely a issue in those fights, but he looked very greasy against Munhoz, even though he was throwing twice as many punches. Aldo changed his style a lot as well. Instead of waiting on his opponent and exploding in burst, he pressured forward with a jab and feints. That’s one the reasons his cardio improved.
And I like how you didn’t respond to my post where I gave 3 perfect examples how fighters get to their peak form even after their physical primes. Jan, Oliviera and Poirier should be completely washed by your logic, yet they are better than they ever were. It’s not all about speed and explosivity. Skills and experience are the deciding factor in who wins 9 out of 10 times.
