Yates, Haig, Mas - what were they thinking? Last chance for them to get some real glory, little risk to their overall standing, and they just let folks ride past and away. Classic game theory resulting in sub-optimal outcomes for all involved.
And Mas...as a Contador fan, I want to like him, but every time he attacks it has the vibe of someone attacking because he's heard it's something a GC rider should do and it looks something like this. Seemingly no intent or desire to actually get away from the bunch ever. So strange. He has been so strong in this race that he should have put in some real attacks. Today, for example, he was likely in the top two strongest riders and should have gotten in top 2 on the stage, but instead he tagged along passively.
