Very solid gap for her now, nobody wants to expend energy now to not have it on the Cauberg, but there are enough teams with domestiques there that there really ought to be some commitment. This is where teams like SD Worx have the problem, because somebody has to work for somebody else and we've already established that it sure as hell won't be Kopecky that does that. Also AVV hasn't looked too great so far, at what point does Movistar decide to either expend Floortje and Liane on Annemiek, or vice versa? Floortje coming back gives them at least one option like that.
I don't think Paladin has enough to hold on on the Cauberg all told unless the bunch really screws the pooch, but she is earning Chabbey and Niewiadoma a free ride. Brown joining her gives them more chance of staying away, but Brown will probably outclimb her too.
Edit: it's Teutenberg in the Trek team car and Magnus Bäckstedt in Canyon's.
