This decision had a massive outcome on the game. Sam Warburton has been not only one of the players of the tournemant, but also the most inspirational captain not only of this world cup, but possibly of the last two. The decision could be argued to be technically correct, but should a player have to control the man back to the ground when it is fairly obvious he will land safely anyway? At worst i believe the decision should be a yellow card and to see their youthfull, exuberant captain leave the field at such an early stage in the game will have had a massive effect on the welsh teams mentality. This is a moment that will be remembered in rugby history forever.
