We know Wilder can take a bit of punishment, that Ortiz fight showed a lot. Joshua was out on his feet vs. cautious Wlad. Wilder won't let you off the hook. This why i think Joshua would fight super conservative. Wilder will go for blood if he senses you are hurt. Better not let those knees buckle.
He ate a flush straight right bomb from Wlad... and got up. I don´t see that as an evidence of a weak chin.
Wilder got knocked down too before
This might be banal but it mostly depends on the range. If Wilder can keep it long range he has a good shot to win it, if it goes anything closer than that then AJ got this imo
I think if this fight will get on the inside or mid distance then Joshua sooner or later gonna pin Wilder to the ropes and bully him, land uppercuts and hooks on him and finally finish him
AJ is a better hooker and has better uppercuts than Wilder and he will have an easier time fighting on the inside with a tall, gangly and lighter Wilder than a short, compact and pretty heavy Parker.
If this fight will be at close/mid range for most of the time that´s all wrong for Wilder, he gotta keep it at long range or KO AJ as fast as he can, I personally don´t think he will be able to do these so I´m picking AJ by a 7-8th rounds TKO now
