You are comparing apples with oranges. Ayuso criticizes his team for not working well for him (like in TA) but he doesn't work for a way better rider and undisputed leader like Pogacar was in the Tour (I'm not even talking about this Giro where there is a argument to be made that Del Toro lost the race because UAE was protecting Ayuso).In relation to Ayuso, you seem to consider it essential that a rider fulfils his duties in support of a leader.
In relation to van Aert, you seem to disregard a remarkable level of such support.
I'm struggling to see the consistency.
Other argument is (and I already said this many times in this forum): guys like WVA should be free, they are too good to be domestiques. If his performances are great when he is in domestique duties, it's not hard to imagine what he can do when he has free rides (Ventoux win, gravel stage, Vuelta 2024, etc). No one can convince me WVA will be remember for how good he was as a domestique than how he was always second, third, fourth, etc when he was racing to win. Poulidor is remembered as the eternal second for example and this is his legacy in 20 years. I don't have any doubt.
