I think Contador did the right thing and he's probably going to win the tour and gues what....nobody is going to care!
However imagine if he had stopped, waited for AS, then finished with him. It would have been legendary, by the far the highlight of the tour, Contador would have been hailed as a hero even if he lost the tour. Cycling has become a dark and tainted sport full of greed, lies, and distruct. Contador had a golden opportunity to restore some desperately needed honor and dignity to the sport of cycling and he blew it. Honestly I feel sad for him and for the sport.
