At the same time, being the strongest rider over 3 weeks is not enough if you don't take advantage of it. Yes, the parcours was a key part of that, but I'm reminded - again - of Scarponi talking about them seeing Hesjedal struggling at the back of the favourites group in the early mountains of 2012 and nobody taking advantage expecting him to drop away, only for him to ride into form and be at his strongest in week 3 - as was his tendency.
Or, for a better and more hubris-led example, the amount of time Jumbo-Visma left on the table in the 2020 Tour de France by deciding to do slow, miserable group rides at the speed of their third best rider and preserve a small lead until losing the race on the penultimate day in the PDBF ITT.
If you let the race come down to a one-stage shootout, then it doesn't matter who was the strongest rider for three weeks, it matters who was the strongest rider on that day. A bit like (uh-oh, gonna upset RHD by talking about a sport other than cycling again now) how France were a demonstrably better football side for the majority of the Qatar World Cup and Argentina kinda fumbled their way by hook or by crook to get to the final... but in the final itself, Argentina were the better team and the deserving winners of that particular match.
