I've been looking up some statistics.
Each year, WADA conducts hundreds of thousands of blood tests on sportsmen across the world.
In 2005, there were 3,909 A sample positives and only 15 of those were for EPO (Lagat's case was in 2003, and the Jones positive occurred in 2006).
So in the 2000's let's say roughly speaking :
There were over a million blood tests taken by WADA (maybe closer to 5 million) in a multitude of Olympic sports.
Perhaps around 150 featured A samples for EPO (based on the figure for 2006).
Out of those 150, there were three cases as far as I know of a B sample coming back negative and the athlete in question 'cleared' - Bernard Lagat, Marion Jones, and Italian cyclist Fabrizio Guidi.
So out of between maybe 1 and 5 million blood tests in the 2000's, the 3 cases of EPO being detected in an A sample, then the B sample 'clearing ' the sportsman are :
1 - Bernard Lagat, still the second fastest 1500m runner in history, still 2 or 3 seconds faster than his Kenyan compatriots can run 20 years later.
2 - Marion Jones - later confirmed to be at the center of the most notorious doping case in the history of American sport (other than the Lance Armstrong scandal).
3 - An Italian cyclist competing in the Lance Armstrong era.
Seriously, it's not co-incidence is it? Either Bernard Lagat was targeted (I can only think of El G/Morocco trying to remove him - not saying it's remotely plausible, just the only remote possibility) or he was doping with EPO, and presumably his negative B sample and subsequent exoneration by the report of a German doctor was the result of American pressure.
Which is it?
