So if he finishes in the top-5, you will say that you were wrong?
If he finishes 5th because Landa, Ciccone, Adam Yates, Bernal, Tiberi, Poole and one other all fall behind him because of injuries, it really doesn't prove that he was a podium contender.
And if he magically has a much higher level next week, good for you, but there have been no real world signs for that to happen. And it's not the first rider you have overestimated wildly (Kelderman) without much apparent reason.
