He has to gain 3 min on Froome whether or not Valverde helps Contador. Bringing another competitor to the front just makes that task more difficult. Assuming their duo attack was allowed to go, it is very easy for me to visualize Contador cracking Valverde on the last climb and moving up to second in the GC. YMMV of course.Netserk said:Quintana doesn't have a chance with a 1 vs 1 duel. He is more than 3 minutes behind.
