I think we can all appreciate Sepp Kuss doing a five second attack to drop his own team's GC threat, getting caught in a hopeless chasse-patate, then sitting in the group gawking backwards just long enough to guarantee that Harper wouldn't be able to make it back onto the group before dropping back to help him. I can only surmise that he saw the yellow shoulders and blue centre of Higuita's jersey, mistook it for Rogla's, and out of habit dropped into line in the middle of the group, sat in front of the guy in yellow and blue, and started doing no work.
