Just catching up on some of the fights, pretty much echo what others have already said; Joshua looked sharp & dominant over Otto, tagged him a bunch of times hard. They saved him from getting battered further, he'd already taken some heavy shots & they probably saved him from being KO'd.
Parker looked solid against Wilder, avoided the power & managed to do tidy work gradually breaking Wilder down, if he'd taken it up a level the final few rounds he might have been able to get him out of there.
Wilder looks broken, it's crazy I remember in the build up to the first Fury fight Wilder talked such a big game like he had that animal inside him, that he had a no quit mentality, he'd faced adversity, overcame it, he had this ruthlessness about him that he had no fear in him.. when you saw the Parker fight not to mention the subsequent rematches with Fury, you can tell he was none of the things he claimed. Maybe he believed all that at one point, but when he tags people with that right hand & they don't go down or don't stay down, he doesn't have it in him to get involved in a scrap or to change it up. It didn't look like he had any business being in the ring with Parker, that's how poor he looked.
