I would say contador today is B. At least he still did what he likes to do: attack. He could have just stayed with sky express, but what's the use for that? if he wanted to test, then he should attack and see if it sticks. So it's not a bad sign, sure he is struggling with his form. There's only two way it will happen, go upward or plateau. For someone who looked like he was done yesterday, he wasn't look so rubbish like yesterday. If he finished like Purito today, then yes, his TDF chance would be game over.
One thing though, I haven't heard a peep, Contador saying about: " my sensation', or I feel 'good sensation', etc. So clearly, he is still finding his form for sure.
On the other hand, TST with rodgers and jesus, was a treat for a sore eye. Looks like if Rodgers got his 'sky mantra down to his notebook', he could ride tempo with them without blowing himself, he could possibly be in the podium.
