As the saying goes, "there's more than one way to skin a cat". Several of the successful clubs have multiple ways of accomplishing a task and they think outside the circle and find loopholes to achieve what they want.
If these clubs can get away with doing things because they know that they can, then good luck to them. Just like in a game, the coach can plan ways to win and they may not be totally within the rules but they are such that they get away with it somehow.
So there is the other saying that Confucius said - "man who just sits on bum and does nothing has the shits"
