I'm surprised no one actually compared CJ performance to a lower level rugby game.
I mean, come to think of it, if a referee leave all these infringement at break down unpunished (for both sides) at the level I'm ref'ing, I can guaranty you players would take the law in their hands... And that wouldn't be pretty.
In the above video you can see Yachvili at one moment pointing a player on the wrong side to CJ, then CJ awards a scrum blue for ball non-playable and you can see Yachvili just raising his arms in frustration... At the level I ref, this kind of frustration would in a few minutes transform to proper booting and punches and end up in a blood bath...
In short, CJ was lucky he was on a RWC final with professional players... Referee that way in any low level local league, and it's a guarantied blood bath!
