I am wondering if AC did not train as hard or follow the training programs, rumors been flying all season that he is not on good shape, but seems the training has worked well for Roman and Rogers as they are very strong and to some extend Jesus and Bennatti.
Think AC might have thought he can still get away with winning on talent only, as he won the Vuelta last year, but he needs to be in peak form to win the Tour and he is not as young anymore. I believe he underestimated Froome, Qunitana and Purito, as he thought, like in previous years would have been able to ride with them and put in attacks, this year his only attacks has been downhill and if he goes with others he can’t keep with them for long.
Think Riis need to have a serious chat with him about how he prepared and what he will do different next year, as Roman would have been better placed if he had not had to do all this work for AC, and he would argue he deserves his own chance as leader in a GT.
Still hope we get to see the old Contador, who can attack and keep away after an attack.
