" "Tadej attacked me for 15 days," Vingegaard explained, "and from his aggressiveness I understood that at some point he would collapse. Those who shoot too much are insecure, spend a lot and pay in the end.""
So it's the same tactic as used before of Jumbo pushing Pogacar and blowing himself up by being too agressive. Which makes me wonder what condition Vingegaard must have to hang on for 15 days and then blow everyone away in the TT.
Edit add - I wonder too what would have happened if the TT was before the rest day and not after. The Giro I praised for doing that (stage 9) but the Tour seems to stick to post rest day for some reason.
