While Kopecky was still somewhat isolated, shouldn't Visma have tried to put a rider up ahead? Not necessarily to bridge to Van Dijk, but to at least not waste that they wouldn't pull anyway.
Finally a group makeup that recognises it might be the best idea to not cooperate with SD Worx when outnumbered... only took a group where two 20-year veterans are the only non-SD-Worx riders for that lesson to be learned.
Kopecky taking 100% of the wind because Wiebes is. well, Wiebes.
