Why don't Bianchi and Telekom ride for their stars?

Jan needs every second he can get - so wouldn't it be sensible for his
team to try to let flat stages end in mass sprints?

Erik needs every point he can get for the green jersey, even if he says
he doesn't care about it - so wouldn't it be sensible for his team to
try to let flat stages end in mass sprints?

Both teams have nothing to lose anymore. Bianchi anyway, Telekom's
Vinokurov should be save as third, too.

So can anyone here explain why these teams do nothing?
