Remco has a history of looking strong in the first half of a GT and failing in the last week. His 2022 Vuelta performance is so far proving to be an outlier and it could very well be that Rogla's abscence has something to do with it as well.
If Remco was out with covid or crash on Vuelta 2023 on stage 12, you would probably be saying the same thing: that he would have (easily) won the event. He was in front of both Roglic and Vingegaard by a hefty margin after all...
And it's not just Remco that's "failing" in the final week. It happened to Roglic, Pogacar, Yates, Thomas, Bernal, almost everybody bar Vingegaard so far. Which finally brings me to the bottom line: Claiming someone would have easily won a GT based on the status at stage 12, 16, 18, 19 (or sometimes even 20) is ridiculous.
