You have to have some results, not winning but some good placings, to get a change. Zaugg did just that the lasts weeks and probably the other captains (Fuglsang, Monfort) knew they didn't had the legs anymore. So he got his one change and took it. Probably not the best name as a race winner, but deserved anyway.
It's not the best thing that nobody focussen enough on a race so a domestique can win. But what really would be worse, is the toppers do not focus and they aren't challenged by domestiques who try to have their one shot!
For next year, I hope Gilbert understands he can't do Sanremo, Ronde, Ardennes, midseason the BC/Tour and then the Vuelta/WC/Lombardia. I think he really wants to be on topform LBL, the tourstage near Liege customized for him and the worlds. Maybe quitting the Tour after the first week is the wisest thing to do. What do you people think?
