The mistake is UnoX still sprints with Kristoff instead of Waerenskjold IMHO!Wærenskjold kinda blew this one. He should have gone early for a monster leadout with Kristoff on his wheel, when Philipsen still had 2 riders in front of him.
In that situation, when they have the field out you can't wait until Van der Poel does his leadout and expect to win. A wattage monster like Wærenskjold, with his sprinter Kristoff on his wheel, should go early, to even the odds and launch Kristoff at a high speed in a tailwind sprint.
This isn't 2015!
