But this is the point. I'm not advocating either way, but saying it punishes well run clubs ignores that other clubs are struggling. So by keeping 100% of your revenue rather than sharing some out, you put other clubs at risk, which means more go under, which means less games and less revenue for you.
Again, I'm not saying clubs should revenue share, but the mentality of 'well I'll just worry about how I run my club' risks actually becoming self-harming. Rugby in England as a whole is on the verge of becoming unsustainable as a professional sport in its current form. If clubs only look out for themselves then they will end up being dragged down too.
