Sagan will probably win green, but I don’t think he will win many stages with Groenewegen, Ewan and Viviani all riding. Quite a bit will depend on how many of those guys can be arsed to ride all the way to Paris
He will grind it out and get intermediates, plus do well on classic-style lumpy stages like stages 3, 5 and 9. Though in the latter I think he will have tough competition from the likes of Alaphillipe, van Avermaet (who’ll be desperate for wins after a poor season), van Aert, and Niki Terpstra who’ll be under pressure to perform for his new team on home soil
