Why I think Joshua's chin isn't the issue. He wasn't used to combinations.

[Boxing Logic]

I see people saying Joshua has no chin but I saw somethikng else. Joshua's chin is above average. The bigger issue along with stamina is that he just expects punches to stop coming after the opponent throws 1, 2, or on very rare occasion, 3. He's not used to people throwing 5-7 punch combos back at him. Outside of Klitschko, Whyte, and Ruiz he's not faced anyone who wasn't scared of him so he has very little experience vs guys who throw back. And Klitschko and Whyte are not combination punchers so even though they weren't scared, they didn't do it either. Ruiz was literally the first time Joshua ever had to defend against combinations and you could see he wasn't used to it. After the first 2 or 3 punches he just put his hands up and closed his eyes thinking or hoping the flurry was over so he could reset or get to safety, but Ruiz kept throwing even after Joshua didn't think any more were coming. Those are the ones that hurt guys. In contrast, the shots he saw coming he took quite well. He's just so clumsy defensively in certain ways that he got hit by a staggering amount he did not see coming. Defense, and stamina, are the issue. His chin is above average.

Nah it was his chin

He was doing the Amir Khan chicken dance all over the ring

He’s been wobbled many times and dropped...he’s not very durable. I know it’s the hw division where anything can happen and he was hurt by shots to the top of the head/behind the ear, which anyone is susceptible to, but he can’t seem to get thru a fight without getting shook up at least once.

I actually agree with you for once.

Ruiz fights like a smaller weight fighter. The heavyweights aren't used to his combinations or even his body shots.

[HeadShots]

His chin is terrible.

There have been 12 people who Ruiz didn’t stop over 10 or more rounds. None of them have the height and reach of Joshua to stay out of range.

Yeah I agree with this assessment, handspeed/accuracy and more than 3 punches he is lost.

Joshua's problem isn't just his chin, it's his recovery power. He gets buzzed and stays buzzed for a long time.
