The sordid corruption that has been exposed within Fifa and the International Association of Athletics Federations is deeply depressing. Yet a far less publicised but more pernicious trend has emerged with sporting bodies attempting to control and manipulate research into the long-term health of their athletes.
You will never be able to completely eliminate the risk of playing any contact sport, particularly in collision sports such as rugby and American football. When men the size of camper vans crash into each other, bones will break, muscles will tear and concussions will occur. That is unavoidable.
Where sports do bear a responsibility is to investigate and fully inform their athletes and the public of the long-term effects that such actions can cause, in particular around concussion. Hips and knees can be replaced in middle age; brains cannot.
Yet spelling out those risks in full will carry a cost, whether it is incredibly brave individuals such as Chris Borland choosing to walk away from a multi-million dollar American football contract aged 24 or a generation of parents who decide that their children should play another sport.
There are three letters in particular that send shivers down the administrators in both American football and rugby: CTE (Chronic Traumatic Encephalopathy).
Also known as punch-drunk syndrome, CTE is a progressive degenerative disease of the brain associated with repetitive concussions. An independent research project at Boston University has identified its presence in the brains of 90 of 94 former NFL players it examined. With the science still in its infancy, the key questions now become who conducts this research and what are their objectives?
In 2012, the NFL granted the National Institutes of Health $30 million (£24 million) for a research project as an "unrestricted gift". And yet as a devastating 91-page Congressional report concluded in May, top NFL officials waged a campaign to steer the project towards employing its own in-house researchers rather than independent experts.
The report concluded: "In this instance, our investigation has shown that while the NFL had been publicly proclaiming its role as funder and accelerator of important research, it was privately attempting to influence that research."
On the other side of the world, a similar pattern emerged. In July last year, World Rugby and the New Zealand Rugby Union presented the findings of a three-year study, funded by World Rugby and conducted by the Auckland University of Technology. Its findings, that more research was needed, were unremarkable.
Yet using the Official Information Act, the New Zealand Herald last month revealed the extent of the discord and disagreement between the AUT's lead researcher, Patria Hume, and World Rugby officials. Hume emailed a colleague saying: "They [World and NZ Rugby] just do not want us to say there is any issue at all" regarding cognitive impairment. World Rugby and the NZRU both deny that they attempted to influence the report.
Closer to home, Jeremy Wilson last month outlined how the Football Association failed to publish a study it commissioned with the Professional Footballers' Association to investigate the prevalence of dementia among former footballers following the inquest into Jeff Astle's death in 2002.
There are many, many good people involved in sports administration who have athletes' best interests at heart. Yet, as these examples demonstrate, the temptation to soft-peddle or bury the risks can be overwhelming. The only safeguard can be that all future research is fully independent, peer-reviewed and kept at arm's length from the tentacles of the sports governing bodies.
Anything else is open to abuse.
