Od dear, the Geezer really believes that Gentleman's Game twaddle.
Rugby has long been infected with drugs, thuggery and cheating for a long time. But because it is a minor sport, it is only reported on page 57 and not the front pages.
Take the case of the Bath Trio, who went out on a public drink and drug binge, refused all attempts by their club and the authorities to be coaxed to take drug tests (apparently they took a voluntary test 5 weeks later).
The bath `Trio were banned for 6 months, being guilty of...
"... unreasonably refusing to be tested and of leaving the club waiting on the two days when tests were requested by leaving the city, ignoring text messages and switching off their mobiles.
None of that was on the front pages of the newspapers. Contrast that with Rio Ferdinand. All over the papers for weeks, 8 month ban and �50,000 fine.
So, in answer to your question, How can the sport clean this up going forward? The best way is not to pretend the sport is anymore clean and gentlemanly than any other.
