Lets have another email. This is from Chris (thanks):
I disagree that Boasson is categorically better to go in a move. A move, he will be with other strongman, and then tactics can be a potluck, you also have the neutralizing of the group strongman, as other's mark him, a natural handicap if you will. In a field sprint, say, with 30 riders, I think Boasson is the strongest rider, bar Cancellara in the move. Without the super leadout man, like Hincapie, Cav could be susceptible to being out positioned, poorly positioned, or boxed. See Boonen over the last 2 seasons. His ability to position himself, in a field sprint, either at the Tour or elsewhere, is weak, when there are a plethora of field sprinters contesting, and a strong train.
