Evans is already calling it doping based on his numbers.

"They put it all on the line, and they really had to with a long-range attack there," Evans said of Leopard Trek, who placed two riders, Maxime Monfort and Joost Posthuma into the early breakaway so they could be present to help Schleck on his voyage through the valley between the Izoard and the final climb up the Galibier.
In ideal world, Schleck's attack should never have gained as much as the more than two-minute gap he enjoyed at the top. Evans described the obstacle the slight Luxembourger faced, even with help from the remnants of the breakaway.
"On a numbers basis, [it was] 20-30km of block headwind [in the] upper valley... we're 40 and they're four riding at the front, with one to nine guys riding behind. They rode incredibly fast in front, I don't quite understand how they made so much time."
