I have a feeling Astana will join Sky in making the pace as hard as possible for Alberto who's weakness will be Giro fatigue. This should play into Froomes hands more often than not as that is the type of race he enjoys. There seemed to be no love lost between Astana and Contador at the Giro so I expect that to continue.
If the first week is wet then Froome may struggle in those hilly and cobbled stages, if it's raining in the mountains that's fine, he's proved he can perform in those conditions.
