You all have forgotten about Lance Armstrong the classics and world champion. Before Lance was diagnosed with cancer he was still a champion, just not a TdF GC winner. In 94 he was second in Liege-Bastogne-Liege and San Sebastian. 95 saw wins in San Sabastian, Tour Du Pont, and a Tour de France stage win at Limoges 3 day after teammate Fabio Casartelli died on the descent of Col D'Dspet. In 96 he bacame the first American to win Fleche Wallonne and won the Tour Du Pont again by July it's suspected the cancer was affecting athletic performance. He abandoned the TdF after 5 days and showing in the olympics in late sumer was less than expected. He was complete different person before and after cancer. Attitudes change when you're on death's doorstep. He came back from cancer determined to be competetive again. I will not waver on my opinion that his rise to prominence and first and probably second tour wins were clean.
I'm a recreational cyclist these days but competed at a very high level as a junior (under 18) and all these years (31 now) I have been bothered by professional cycling being designated a sport dominated by cheats and dopers while nary a mention is made of track and field, swimming, soccer, and let's not even mention the steroroid use in football and baseball. It just seems like professional cycling is held to a higher standard in terms of doping.
