That was for HGH.......not all PED's. Again people seem to be skewing fact to support inherently weak arguments. HGH is a relative new comer in terms of PED use in sport. The test for HGH has been recently synthesised. They weren't even sure it would work......now they have proof. Couple this with the fact there is a very small window with which the test is accurate it is indeed difficult to catch athletes using HGH.......expect it to happen more often.
Those guys you listed flunked for steroids or diuretics (post-fight i might add). The NSA does not test for HGH or EPO so they have 0% chance of catching anyone. USADA does test for HGH and EPO so they at least have a chance.
Additionally 0% = no deterrent in place.
