Do you have any proof? The guys at the TAS don't, either.
Listening to the stupidity in itself yesterday (I mean Prudhomme, of course) made me definitely sick. OK, I will say it.
I'm not impartial this time. On one hand, because Contador is one of my personal sports heroes, up there with Rafa Nadal and Pau Gasol. On the other, because I have some inside information, that makes me strongly believe in his innocence.
