Because he didn't have that amazing last 1k van der Poel had. Oh, wait, you never actually read my comments, you just read the part about me saying it was luck that created these conditions so that he still had the opportunity to do that 1k raid, with all the people commenting on the "luck" part, and ignoring the fact that i said from the start it wasn't just luck because nobody else could have done what he did, but without a huge part of luck, he wouldn't have won?
I was comparing his Amstel win to his Strade win. In Amstel, he got lucky to end up in a position that he could still win from a lost position, considering he'd been dropped, had made tactical errors, and wasn't the best rider in the race. He was however the only rider in the race that could do that drag sprint to snatch the win from an impossible position. Conditions served him, getting in a chasing group that worked together, and Ala and Fuglsang not riding. Had those things not happened, nobody would be talking about MvdP in that race. In Strade, it was the other way around, there was basically no way he was going to lose that race.
