at first i thought AC was wrong to attack his own teammate at the last km of the stage. however, after i realized that it was Rodriguez who attacked first and AC counterattack in order to gain time on his rival, and that Vino has no legs to respond to Rodriguez anyway, i realized it was a great move by AC to gain 10s from AS. esp since it didn't look like Vino has the legs to respond to Rodriguez anyway.
it would be a different matter if AC went without Rodriguez, but he didn't do that.
