This is some fine trolling here. Yes, Contador dropped his own attack NOT to try and help Rogers salvage his podium position, but because he wanted to avoid having to respond to a then-unknown, but apparently expected, diabolical attack from Froome.... Where do you dream this stuff up?
I'm saying he didn't want to come back to the peloton after Rogers' collapse, because he was called the tempo had increased significantly (which was the case) and apparently Sky prepared an attack. Surely I doubt Contador is afraid to be beaten. He saw too much in his career. So that was just an assumption.
Also, he was out of the saddle yesterday (Porte was digging a little deep yesterday).
They stand up on the pedals not only for maximum effort, for some dynamic variety too.
