Now I've got it. Everybody dopes, right.ITF is behind the whole scheme, right. It wouldn't suit the media and sponsors if the scheme is to be released somehow, right.
Fuentes said in 2006 20% of his clients were tennis players. That's several dozen players for him alone, and he tends to only work with top sportsman.
Armstrong's dope doctor, Del Moral, was the resident doctor at a top Spanish academy for 15 years. Not some nowhere place, but the base for Safin, Safina, Errani, Ferrer and tons of others.
All sports that implement serious testing catch dopers by the bucketload, but strangely enough, tennis catches nobody.
That leaves two possibilities:
1) Tennis, which has the weakest testing in all of sport, is clean.
2) Tennis catches no-one because it's not looking.
Even a cursory overview of the current anti-doping setup shows that 2 is the case.
