No. Thats your opinion and one that I also share but his record is what it says it is. Undefeated. Get over it.
He tends to get rocked and stiff legged quite easily, but that's as much down to his awful balance and footwork that sees him take punches flush on the kisser with no ability to ride with them. In that respect his chin is actually quite respectable, since most people can't keep taking shots like that and remain standing. He's got great recovery abilities and fighting heart though, which help him get back into a fight he might be in danger of being TKOed in. Fighters need to make sure they absolutely put him away since he remains dangerous however long he's on his feet.
I think not. Joshua got up from Wlad's right hand. Wilder wouldn't. British heavies in general do not take a good punch, but neither do skinny legged top heavy heavyweights. Wilder has 18" legs...my neck is as thick.
