It seems that a genuine difference between football and rugby is that in football the fans, players, managers and commentators will admit to the cheating and wish something was done about it, only the authorities seem to bury their heads in the sand. Unfortunately in rugby the fans, players, managers, commentators and authorities are all living in a dream-world about the level of cheating going on.
I have played both games, and enjoy watching both games, claiming that rugby is in any way played in way that is intolerant of cheating is just ignorant of reality.
Rugby league however has provided a true example of a club enforcing a proper moral stance, when they sacked a very successful manager for verbally abusing a minor member of staff, although I think this says more about St Helens as an individual organisation than anything about the sport they represent.
