Does Hindley really want to do the Giro that much? Just so he can be team leader? I can understand him wanting to go to the Tour as team leader but that wont happen now that Roglic is there.Hindley is a better GC rider than Vlasov - I'll also add that if hindley does not do the giro then he will leave the team - Jayco are very interested.
Maybe Jayco (& the Saudi money) can persuade Hindley if they promise him Tour leadership.
