I don't think he went to any greater lengths than anyone else, I think his whole regime was a little more professional and planned than other teams though. I don't think he was necessarily anymore doped than any of the other contenders at that time. It wasnt his doping that was a problem for me, it was the fact that he was an utter prick.I don't think people were surprised he was doping, more shocked by the lengths he went to. I know i was amazed at the complexity of it all.
it will be interesting to see now how much he will be sued for by people who sponsored him.
Also, as he had the majority of his Tour career with his team sponsored by the US Postal Service, his sponsor was actually a government/state outfit. Which means he defrauded the government and the tax payers out of significant amounts of cash. Be interesting to see how that turns out.
