The thing is, I don't know if it was loyalty to their charges, disquiet within the team or what, but they never wanted to commit anybody other than Demi to the chase, Demi isn't really a time trialist, certainly not compared to AVV and Anna VDB, and she's certainly not a "pull six minutes back on her own" time trialist. That's just not playing to her strengths, but with what happened in Rio I can't imagine the thought even crossed the mind of the DSes to have Annemiek and Anna ride to control the break for Demi, even if Anna's been willing to do that for SD Worx. Sure, it might have been smarter in retrospect to have brought van Dijk or Brand or Pieters as a workhorse instead, but the four women they took currently rank 1, 2, 4 and 6 on CQ, and 1, 2, 3 and 5 on the WWT. The lowest ranked on CQ is Vos, and the lowest ranked on the WWT is van der Breggen (no, really). Vollering currently leads the WWT, and with her wins in Liège and at La Course has won the last two high profile one-dayers on a similar kind of finishing profile. The most logical name to leave out would have been Vos on that basis, but even then she's the obvious best weapon in a sprint and she's only, you know, Marianne Vos. Then you have the problem that you're going to have competing goals because the only one of those that even the guys in the car thought was expendable was Demi, and that's probably more only because of the others having seniority over her. Other teams that don't have the same strength in depth could afford to take a rider or two who knew they were only there to be helpers but making it to the Olympics would be honour enough - but with the Dutch having such weapons in their arsenal, it's not like many other teams were going to commit to help the chase, especially given one of the key candidates to do so - the Poles - managed to circumvent that requirement by having Plichta in the break.
