The unfortunate thing for Contador is that he seemed to have his best chance in the Tour for a few years going into the 2014 Tour but he crashed out. As many other riders have discovered, those opportunities come and go and when the form is really good you have to make the most of them but of course crashes and bad luck come into the equation. 2014 may have been the last really good chance for Contador to win the Tour but I was still looking forward to a battle between the favourites this year and that scenario already seems unlikely unless he recovers quickly. Motivation and toughness have never been a problem for Contador but injuries, illness or crashes can ruin anyone's race. Still the first week is only half done and other GC riders can also suffer bad luck. Geraint Thomas is struggling with injuries and he is usually important for Froome especially now that Porte has left Sky but the Sky squad has depth that others don't.
