I agree, it's just that he's not the same as other riders. You compare him with Vingegaard, Almeida and Lipowitz. None of them target 1 day stage races for which you need explosiveness. Evenepoel tries to do both, and he is no Pogacar. He can't just do both. He needs specific preparation for long climbs which influences his explosiveness, and the other way around.
So even though I expect him to be very good, I don't expect him to be as good in Catalunya as he would be for the TDF, because for the TDF he will have trained on longer climbs even more than he already did now, since for now there's still LBL to take into account.
