Curious what the consensus is these days? I'm not so sure Cavendish can live up to the "The World's Fastest Man" slogan now. Kittel is just so strong. I can't remember the exact stage, but last year there was an incredible slow motion shot where Cavendish was visibly surprised as Kittel overtook him for a stage win in a bunch sprint. A few years ago Cavendish being outsprinted was almost unthinkable.
If Cavendish can't consistently outsprint the competition anymore, is he still a valuable rider for OPQS? An important point, as from a manpower perspective Cavendish is hugely expensive; a massive chunk of the 9 man squad is used to provide his sprint train. His entire value to a team and the exposure he brings their sponsor is so heavily based on his sprinting too.
The battle between the two was for me one of the most exciting aspects of this years tour, its a huge shame we didn't get to see it play out.
