No way, do you really think most heavyweights could have got up and fought back after taking that right hand off Wlad?
Joshua has a Glass Right Temple!! Even the Commentators said "It was that Left Hook to Joshua's Temple that he never recovered from" during replays of the knock-downs from round 3... Forget the Jaw go for the Temple!! It's his Tender Sweet Spot!
You missed out Sadam Ali and Julius Indogno both have awful chins and should definitely be in the top 5
Tabiti doesn't have a glass chin, there's a lot to fault him on, but glass chin isn't one of them. Dorticos is a devasting puncher.
