With nothing to base it on but a hunch, I think that Lance was probably doping for the 7. But.......I also feel that just about all the riders in the Peloton are juiced.
Lance is a badass dude, dope or not.
I would love to see him win the 2009 Tour, with every test (nothing new) and his training prior made entirely public, not to convince me of his "cleanliness" but to showcase a cycling great.
Lance is almost the last man standing from his cycling era, everyone around him (that he beat handily) are proven dopers, or so close to the flame that only a moron would assume their innocence.
Lance must cement the legacy by riding clean. Lance is still competitive, and can break another Tour record while he is at it. The whole Phelps thing (don't ask....) being "Super Tested" and such, drives home the public's desire to be assured that an athlete is clean. Lance can see this.
After this year's Tour, you know Lance is thinking he can come back and clean house. Clean.
Getting a solid team............now that might be a different story.
