Just for the record, Vino was found to have someone else's blood, not taking drugs.....
but that is still against the rules, so a minor point.
As far as I am aware, however, Astana had no positive tests last year, had the winner of the Giro and the Vuelta, and are a professional team (now)> Having Lance back is no bad thing, and racing against them (Lance and Alberto) gives the younger riders in the test Team the chance to compete with the best riders, one the best ever, and the other, the best at the moment. Imagine how good it would be if Carlos beat them both.......
Everyone is working hard to have a clean sport. Don't judge Teams on the past...or there would be no Teams in Le Tour.
