i found this very interesting. velonews had vaughters on their tdf cast this morning. they asked him various questions, including this one.

That raises the next question... he's gone through a two year suspension for EPO. Why regard him as a moral authority for clean sport?

Vaughters: Well, the first thing to realize about Dave is that he could have fought and won his case. There was one expired vial of EPO found in his home. He never tested positive and the evidence was minimal. However, when asked the question, he told the truth. He took his lumps. We all knew that Dave was a massively talented rider that didnt dope for most of his victories. The pressure of sponsor obligations and performance pressure to live up to being "the next big thing" finaly got to him.

Anyhow, Dave told the truth and now he's back and doing well, the correct way. He never used the "I've been tested 1000 times and never tested psoitive" BS... He just told the truth. That's why I love Dave.
