Interview with the JV directeur sportive is interesting - plan was to get WvA in the big break, because they were sure that if WvA was in the peloton with his current form, that nobody would help JV bring the break back (and presumably they didn’t want to commit riders to do that for the green jersey). Unfortunately a break of only 3 went, which absolutely wasn’t the plan. Clearly WvA gave it his best effort from that situation though.
I don't get why they didn't leave the 10 man break that Laporte was in go. Laporte was the best sprinter in that group, they could have done no work in the peleton and Laporte could have done very little in that group with his teammate in yellow and very good chance Laporte goes into yellow at the end and they just swap and he gets the stage win. It made no sense why WVA was chasing that down.
