A benefit taking 7th instead of being in podium chances?
It's a combo of Degenkolb's own fault, being too eager, and a racing indicent.
Degenkolb becomes belligerent as MvDP passes him.
Instead of giving in, behind MvDP, Degenkolb gives him a 'wing' to force his place - when just in very same moment Philipsen - totally coincidently and without any fault at all, looking ahead on hard cobble section - moves right in MvDP's and Degenkolb's direction.
I write it again - I've been keen of Degenkolb for years, but neither Philipsen nor MvDP is to blame here.
