I think Boonen wants to get it down to 3 or 4 riders. I don't think he likes the big group. Wasting too much energy.....Cance might end up riding away from him in the last 10-20km.
Same story as last week. Boonen too jittery, wasting energy all over the place. Then Cancellara will make a move closer to the finish and he'll have no response
EDIT: And there he goes. Didn't expect him to do it this soon
