Trust me, Joshua at that point had serious doubts, he was totally dejected, you could see it in him the way he looked at the floor etc etc. Watch it again.
I think we get an AJ vs Parker type of performance in the rematch with AJ boxing from the outside not getting involved too much
Joshua was doing well on the outside. It was just on the inside he was getting bashed up. Same thing happened with Parker, but he was smart enough not to trade hooks with the blob. That's how Ruiz got to Joshua in the 7th.
Everytime Parker worked his way on the inside against AJ the referee stepped in and pulled him away. Parker had no chance of winning that night. I just hope we get a fair ref that won't do the same with Ruiz
