Conor's never knocked out anybody the same size as him or bigger. Even when he won the lightweight title off Alvarez he was bigger than him and he was coming from featherweight. He hit Diaz multiple times with the left and still couldn't put him away. Dude needs to go back to feasting on small ass featherweights.
It's the Pacquiao effect after that Hatton fight the media created a false narrative that if he touches you it's an instant KO
