I'd say AJ fought smart. Ruiz had no answer for AJs movement. It was for Ruiz to change the momentum of the fight and he didn't. I think it would have been foolish for Joshua to move away from the gameplan and risk getting caught trading again.
Wilder definitely has a chance of getting the ko against Joshua however Wilder has never fought a puncher like Joshua. It could come down to who tags who first, and I could easily see Joshua knocking out Wilder before Wilder gets a chance to land his straight right hand.
