no question, the history of bike racing is full of folks seeking to improve their performance in whatever way they can.
It could be argued that Lance just didn't know when to tone it down a bit and avoid some of the scrutiny. You don't want to be the guy that the authorities decide to make an example of.
It could also be argued that he might not have been penalized so much if he had been a nicer guy.

To counter the "don't get caught' argument.. I think LeMond serves as an example of the right way to succeed. Like Lance, he had physical problems to overcome, but LeMond seems to have won the Tour without doping, or at least without getting caught doping?

but yeah,.. there are a variety of lessons to be learned from Mr. Armstrong.
