Cav's rainbow jersey is easy to spot, especially in overhead shots and it makes fascinating viewing to try and follow where he gets to. For a long time in the run-in yesterday he seemed boxed in, with 2-3 riders from other teams in between the Sky train and himself. Then as the sprint wound up he seemed to move left (right in the head-on shots), well away from any remaining Sky riders... and still made it. Masterful.
