He has said he simply doesn't feel as strong as the other guys in one day races. I can understand why people think he should be able to do better. In stage races he races so much like Pog, with the good sprint and mean mountain watts. But he just can't as it stands.I honestly do think it's interesting why he's so far been bad in one day races. I think he was okay in Lombardia, but just blew himself up trying to follow Pogacar and Mas.
I think mostly guys like Vingegaard and Landa maybe just overrace and have a peak by Itzulia at the latest after which a monument is just too hard if you're not fresh enough.
If he only did Fleche he would've at least gotten 2nd.
