He’s copped a lot of online abuse,” Schmidt said. “The only thing I’d say about ... the defence of Carlo, there were just over 54Gs of force, direct force that went through the neck, along with almost 2200 rads of rotational force, which is enough to cause a serious injury. “Not to a rugby player who is as well conditioned as Carlo, but he’s probably best just left to take a deep breath. “We’re all aware of Newton’s third law [of motion] that for every action there’s an equal and opposite reaction. When that force hits him and the speed of his head collapsing down, he recoiled out the back of the ruck.
