I'm pretty sure Boonen won't win, and neither will he next Sunday. He performed badly this Friday, and is not yet in shape. Paris-Roubaix, maybe, but Cancellara has the better odds for that at the moment.
Great race, very entertaining to watch. Sagan did everything right, especially attacking himself. Boonen once did the same thing in the Ronde van Vlaanderen 2005, being the best and the best sprinter, instead of having to counter everyone else, jump away yourself.
My favourites for De Ronde this Sunday:
1) Cancellara 2) Pozzato 3) Sagan
in that order.
