In my eyes, Cav is already Tour sprinting champ, again. He's just been edged by the less notable points-taking in non-sprinting stages. Still, much respect to who takes the official points lead by the end of the Tour.
Yesterday was described as easy for Cav, especially with the overhead view to see how much space he had. Yet without his main support (Renshaw), and the fact that there were good chances of having the door closed on him from both sides of the road, I think it was a pretty skilled win beyond his legs.
I imagine HTC playing single-tracked for his campaign, arriving at the sprint with the majority of their roster. Martin's got the pace to be a prime leadout man if he has to.
