2011 Tour probably the cleaner
You don't demonstrate anything with these 2011 tour statistics ...
Contador and Rolland improved their results, Peraud fell last year en route to a top 10, Basso was Nib's domestique in 2012 + age. Cadel doubled with the Giro last year + age. Sanchez probably got too old too.
Plus from a logical point of view you could say the other way around that the top 10 contenders in 2011 were clean and in 2013 the speeds were up and the dirtier ones reigned (more likely in my opinion).
Andy was probably juiced until 2011 but probably not anymore (...although he was was much much better during last year's Tour) so he doesn't deserve much interest in the clinic
