Ross Tucker at the Science of Sport blog has been doing yeoman's work discussing doping. His Renee Anne Shirley interview is worth reading.
RT: How would you sum up the health of sport’s anti-doping as of today? And more specifically, did the Commission’s report do anything to change your perception?
RAS: The WADA Independent Commission’s Report has not surprised me. While others have been expressing amazement about the depth and breadth of the scale of the doping uncovered, I expected this. In fact what has been reported is really the ‘tip of the iceberg’ of what is taking place in Russia in athletics and in other sport (Summer/Winter Olympic sport). The saga represents a window into the problem of massive doping coupled with corruption that pervades major sport today.
But while others are getting caught up in the fascination about “second lab”, secret agents in labs, bribing corrupt officials, tip-off to athletes before testing, and the fact that we are dealing with post-Soviet Russia, this is not a rouge country standing alone. Much of what we have been told is known/suspected for years but is prevalent (albeit at a less sophisticated scale) in other countries today. The Soviet/GDR techniques have been learnt by many and are being used extensively by athletes/coaches/entourages across the globe in order to win at all cost.
