Who waited for Chavanel when he had 2 puntures in stage 3 while wearing yellow? No-one. It is hypocritical to raise these points now.
As others have said:
Bruyneel:
“In the heat of the race and the finale, you cannot say to Contador, ‘wait for Andy.’ Andy didn’t wait for Contador on the cobblestones, either. You can’t say to Sammy Sánchez, I’ll let you go because I’ll wait for the yellow jersey. No, there are no gifts in this race.”
Riis:
“Sánchez and Menchov were going full gas. It won’t help to criticize. For us, it would have been better if they had waited, but we cannot expect any help in these circumstances. I think Contador waited at the beginning, but it took awhile before Andy was on his bike again. How long can Contador wait? I don’t know. Of course we’d have hoped he waited more. I don’t want to create a polemic, but how many guys crashed today? Nobody helps them, nobody waited. That’s how it is.”
