Lance's defenders
Let's say for the sake of argument we throw away a substantial amount of circumstantial evidence. There's still the fact that Lance won most of his tours by minutes. (save 2003) At times, he could have attacked to gain even more time. He focussed on the Tour only, had a strong team, etc. but he was in the range of 5-10% better than the competition...most of whom are known dopers. If you can believe that Lance is that far superior to the competition clean, okay, end of discussion. I have nothing more to add.
A recently posted interview with Joe Papp stated, "A certain percentage of the public will believe you're clean no matter what the evidence." I think there are still quarters where Tyler Hamilton, Roger Clemens and Barry Bonds are defended.
