I think that's what also makes it fun, if he finally knows what he is doing. The standard for Van der Poel grand tours at this point is just attacking for the sake of attacking, even if it does not make sense. It makes very little to no sense, in most cases in fact. If he rides with half a brain and starts marking some stages, I think it'd be great to see him in the medium mountain stages (Laruns, Issoire, Belleville-en-Beaujolais e.g.). I think he could do more there than most would anticipate. Poligny should definitely be a target.
Knowing Mathieu, Nogaro and Morzine are more likely.
