All those, even the likes of the great Roger Federer, who said 'put up the names of tennis players involved in match fixing or shut up' - give yourselves a swift uppercut.
That predictable jerk of the knee followed the BBC/Buzzfeed story alleging 16 unnamed players (including eight in the current Australian Open) who have ranked in the top 50 (and at least one grand slam champion) were allowed to continue playing for years in spite of being highlighted to the sport's anti-corruption unit after suspicious betting patterns around their matches.
While it's true allegations without names unfairly coats all in suspicion (visited on Novak Djokovic and Lleyton Hewitt afterwards), calls for the players to be identified demonstrate naivete and little knowledge of what happens behind the scenes when such claims are in play. It also ignores the way many sports bodies are abrogating their responsibilities.
Proof can be elusive. You can bet the mortgage libel suits with a daunting array of noughts would have swiftly followed any media identification of the players. Sometimes caned for "sensationalism" and "speculation", it is also not unknown for journalists to experience the twin frustrations of a legal letter followed by their employer's decision to drop inquiries rather than face the costs of a legal fight.
The tennis allegations followed recent revelations involving Fifa, the International Association of Athletics Federation (IAAF), cycling and cricket - of either corruption, doping, match-fixing or a combination thereof. Such disclosures have often been led by the media (Fifa, cricket's 2010 spot fixing scandal after which three Pakistani cricketers, one of whom is currently touring New Zealand, were jailed after a video sting by a British newspaper; plus the Lance Armstrong affair).
