Simon Halliday departed his role as European Professional Club Rugby chairman on Wednesday with a warning that World Rugby is sleepwalking its way towards disaster over brain injuries; after revealing his own children do not play the sport due to safety concerns.
A former England centre, Halliday is one of rugby's longest-serving administrators having served on the Rugby Football Union Council as well as at club level for Harlequins, Bath and Esher.
In a candid interview with Telegraph Sport, he reflects upon the bruising battles to form an eight-year agreement between European leagues and unions with a Club World Cup starting in 2024 as its centrepiece.
However that blueprint for future prosperity is overshadowed by the existential crisis that rugby faces over a concussion lawsuit involving dozens of former players. That has hit close to home for Halliday whose wife has banned his young sons playing rugby while the elite game remains a frightening spectacle.
World Rugby has commissioned studies examining the effects of fewer replacements and lower tackle heights, but Halliday insists the governing body must act far more decisively.
