After the tough 12 months Belkin has had, the sponsor and the team will be more than happy to have 2 riders in the top 10. Podium or not, to have 2 riders in the top 10 is a good return for the sponsor. If they ride sensibly, they can still maybe get on the podium as Contador and Kreuziger will take risks and could lose time. Let them burn themselves out. If it doesn't work, then they get 4th and whatever other placing they have, which the sponsor will be wrapped with. It's all about preserving those high placings rather than risk attacking and lose them.
And fatigue for all we know could be getting to Ten Dam and Mollema and if that is the case, then they need to ride sensible.
