After reading about Pogacar wanting to leave the Tour after stage 5 (when his girlfriend crashed) and subsequent comments about morale, I hope there's no mental problems.
Imo there's seperate things.
1. The wanting to leave the race after the gf crashes just seems like an initial reaction / PR piece based on that initial reaction
2. All the talk about psychologically cracking seems just *** to me. It tries to A) make the rider more relatable,) oversell the story and C) preserve the myth of the rider and rivalry. Nobody wants to read the story of "we found out rider A is just better than the other right nwo"
Given that the gap between them was under 2 minutes, and Pogacar got dropped while Kwiatkowski or whoever was pacing the main group, I find the notion that it was mental to be a combination of pure comedy and actually deeply insulting to the rider. If you really think about it the implication is that Pogacar "could have been up there with Vingegaard on Loze but decided not to/was mentally weak"
I can have my criticsm of Pogacar but it's not that he's mentally weak. In fact it happens quite a lot in other sports that underperformance is attributed to mental weakness as some sort of "I'm a fan of their talent but they didn't live up to expectations so it must be mental weakness" in some weird as *** way
