Cycling had a long and dreadful history of doping-related deaths.
The rampant doping in other sports reflects an unwillingness to learn the lessons that cycling learned the hard way. Armstrong never failed a drugs test, because the tests were a joke. The biological passport isn't a magic bullet, but - when seriously enforced - it places hard limits on what dopers can get away with, no matter how devious they are.
Most sports are in denial, because they don't want to endure the painful process of actually rooting out the drug cheats. They have weak, ineffectual anti-doping programmes that are trivial to circumvent, then imagine themselves to be clean because of the low rate of positive tests.
