Interesting statements. Did you not watch Amstel this year? Sky sacrificed their entire team for Kwiat, who was nowhere near top form. Or what about Vuelta 2011, they didn't exactly ride for their strongest rider from the start...
Kwait was not strong at all but SKY had other cards to play . Today they had more than one as well
As for Vuelta 2011 ...that was Sir Wiggo ...that was about something else altogether
Finally
1. No one stoped Nordaug catching Vockleur ,etc
2. Even if Moscon or Nordaugh were up there with Vockleur alone I doubt either would have done better. Tommy V is a master of this type of racing
3. If you don't think Roche was the best climber in the race well you didn't see the last climbs and I am not going to spend any more time trying to persuade you otherwise. Some people have a very myopic vision
