Philipsen and Bouhanni got a little close and personal in that sprint.
I suspect Ewan is rueing his error watching this from home, but all this talk about him taking 6 stages if he'd have stayed upright are a little silly. As Red Rick mentioned, van Aert won two stages last year and can't get close to Cav this Tour. Cav didn't look too far off Bennett and Scheldeprijs and has taken a few steps forward since then, so he'd probably have given Bennett a run for his money in the hypothetical scenario that they are at the Tour in different teams.
The somewhat weakened field doesn't diminish from what is an incredible performance in what could be a history-making Tour for Cav.
