I think it mainly shows how weird it was to hype someone as future dominant GT winner after barely any big climbs at top level races. Meanwhile his wins were generally ITTs and hilly races where he beats a group on the flats, and I think this has been extrapolated to GTs way too much. In all honesty I think the crazy expectations and goal post moving is the main reason why Evenepoel is a polarizing figure to begin with.
As far as I understood yesterday was his first competitive 40 min + climb. He is 20 something, had a terrible crash, didn't compete for 9 months, starts his first stage race longer than a week, the hardest in professional cycling and some are expecting him to go ahead and win it. I really hope he didn't. On top we discover he is a poor bike handler and most likely traumatized by the Lombardia incident. Was it irresponsible from the team to throw him in the Giro? If they had expectations then yes, if this race is approached as learning and evaluating then no.
