You've clearly never boxed before my friend. He went nearly 30 mins and started slowing down after round 8 after 24 minuets for fighting, his punch output went up as the fight went and his most active rounds were 6,7 and 8. Do you know how hard it is to maintain your cardio for that long when throwing 450 punches and absorbing shots, you have to constantly keep moving and have your hands up. The fact he went that long is very impressive.
Only fight he gassed was the first Diaz fight. The second fight he was tired but finished strong and got his second win, when you're in a dog fight like that vs a bigger man you're gonna fatigue. Diaz fatigued even more and he's suppose to be a cardio machine. So you shit on Conor for gassing in a fight he actually won vs a bigger man who's known for cardio?? Are we going to say Gus and Jones have bad cardio cause they were both gassed?
That's the problem with people like you. You have no realistic perception of what happens in a real fight and what fighters go through.
