One, a pool game. The other, a World Cup final.
What would the mitigation for the first one be? Scotland 8 gets the ball, Kriel thunders into him with head on head contact. No sudden change of direction by the runner as in the Cane case, it's not a reflex tackle, there's not even an attempted wrap of the arms. Cane was virtually stationary, Kriel was charging. Not even referred.
