He's probably scaled back the dope with Astana he hasn't done a lot (I would back him to win the Commonwealth Games RR without dope as the field isn't that high and Cav basically had to ride on his own) since he's been with them, and I don't think his results at QS were that special, he won the TDU and a stage of the Tour of Poland, why not ramp it up to win a Vuelta stage or something.
I'm also well aware that Contador was named, I think just about all the LS riders from 2005 were named (except for people like Vino who wasn't on the team yet) or have the stigma attached next to their name for having riden for Saiz = client of Fuentes. Just as there are two AC's in the documents which is also a fact. I'm happy with the idea that Contador dopes, getting called up at the 11th hour to ride the Giro, a race he hadn't trained for and end up winning the race and when CERA use was rampant is a bit suspicious in my books.
