Will Alaphillippe even ride? He's 22. I think EQS might want to hold him back another year or 2.
The cobbles are on stage 4, so I think we can take it that everyone's still going to be in some sort of contention at that stage. I would say that would be an opportunity for Sagan to get into yellow if he puts in a decent TT and stays in touch up the Mur on stage 3. Only problem with that is Tinkoff would surely have learned from the Giro that their staff aren't up to the task of defending a leader's jersey from day 1 through to the finish in a GT; I think the ideal for them would be if Tony Martin wins the opening TT, or someone like Gilbert, Cancellara or Kwiatkowski takes yellow in stage 3 (Mur) or 4 (cobbles) and Trek/EQS/BMC control the race all the way through to the TTT and the Pyrenees.
