Cav had nowhere to go and got boxed in and almost ran into van Aert so he had to let up. His mistake is not moving right with yards before the finish when he had the opportunity. Had he moved right instead of staying straight and even moving left a little, he might had walked away with a win. Plus he went ahead of his leadout man with 200m to 300m to go didn't he? Two bad mistakes cost him this win. van Aert played it cool and took the win.
