Absolutely true, however most NFL players including Peterson have much more muscle to support the knee compared to Chiesa.
Yeah that’s what I was going to say is their main advantage in protecting the knee joint. A lot more muscle there. AP was 1.85 metres - 100 kg. I doubt Chiesa weighs more than 75 kg, if that. But then that also means he isn’t experiencing the force of 100kg plus pads on those joints too.
But my point wasn’t really that knee injuries are more likely in one or the other, it was that with modern surgical techniques, ACL tears are no longer the death sentence for speed and explosiveness they once were. And AP is a good example of that.
