Contador rode smartly today, but isn't in 2014 shape. Had he been, he would have attacked with Aru and then Froome and Porte in person would have had to jump.
Aru has always made those bold attacks when he wins, taking advantage of his rivals frankly underestimating his potential, which may have been justified in the past, but now no longer. It will be interesting to see how Aru handles his new-found prowess, because he won't be given a leash at all from here on out. Not that he was given one today, because he simply was flying. And I said he would be, because I saw him win the Italian national championships after the Dauphine, where he was already very strong. Go Fabio! If only he were a better TTer, he could really stick it to Froome and Sky this time.
Sorry for the digression, but this does revolve around Contador, who must find it difficult to see a younger rider be able to light up a course the way he used to perform. It doesn't seem he is able to reach the level required any longer, though I wouldn't have thought, even at his age, considering his pedigree, he would not be able to still muster it with all out dedication. The only thing that can be hoped for Contador, is that he planned to reach peak form in the second and third weeks. But this is probably wishful thinking.
