You are over analyzing this. The only person who truly disrespected his opponent MIGHT have been Rockhold.
Werdum was rocked before he went chasing. It is common for a guy to go for a desperation shot or punches when they are badly hurt. He was also feeling the pressure of fighting in his home town.
Aldo did not disrespect Connor either. He went for a punch that was available but Conor read it and perfectly countered it. You dont go nine years undefeated by looking past a fighter, especially considering Aldo wanted to win this fight more than anything. If anything, he could have been feeling pressure fearing defeat.
