IRFB International Rugby Football Board. Rugby League is a northen variant of rugby. It is a far less flowing game than rugby union. In league two lines of forwards face each other across the whole width of the pitch. Forward play dominates with many small set pieces.
American football is static by comparison to union and league.
Here tedious set plays are intersperced with extensive breaks. Vast armies of players flow on and off the field of play. There is much running off the ball since most players don't seem ever to touch the ball. Worse the football is expected to be thrown forward. They play at the Valley which is the Charlton FC ground.
