I haven't see it Trogg, but from reading up, it's the brainchild of Ben Ryan who coached Fiji Sevens to Olympic Gold. The game is aimed at getting younger players into the game, as it doesn't take as long to learn all that's required as the full 15 a side game or as tiring as seven a side which is played on a full size pitch.. Hopefully it will spark some interest and draw younger players in, especially should (when) England win the World Cup on Saturday, the interest in rugby will spike and hopefully clubs might give it a trial to get younger players playing at least a form of rugby, that they can progress from to the 15 a side game.
