I'd love to know exactly what he did in that moment.
I recommend this video from the greatest rugby player of all time, Dan Carter. When he steps up to take a kick, he pushes his toes into the ground and pretends he's bare footed and feeling the grass beneath hi feet. That helps him transition from a frenetic mental state to a calm one.
It's one of many simple and replicable techniques to help you calm yourself at a moment of pressure.
