No I don't think a single second Geox was clean. But obviously Saunier Duval-Geox didn't have such a well organized and dificultless working system as Rabobank & co.
Saunier riders were either doing very loco things and got catched sooner or later (Ricco, Piepoli, Mayo) or didn't perform as well as the guys on bigger teams. And talking about Cobo "Somebody CAN have that much luck to get away with it".
Saunier had a bunch good 2nd line riders like Gomez Marchante or Jeker, of course. But even big riders like Simoni or Mentsjov weren't on their highest level at the team. Simoni actually rode better again with Savio in 2008 until his hunger knock and before finally getting old one year later. Also Millar rode worse there than on Garmin.
So that let me implicate that except their high-risk Cera/Epo activities Saunier/Geox programm was very amateurstic compared to the one of Rabobank.
Given that 1 blood bag or a lower programme is affecting Mentsjov that much let me state he is a non talent for a top rider.
And I forgot about Isidro Nozal. But that's why I said "One of the most". There should have been other experiments in Spain of Fuentes I could've also named.
