None of what you're saying is relevant to what I was critical about. I'm not saying sport is still like the 1960s, your way-of-thought calling someone struggling mentally 'unstable' is something from the 60s.
Having a tough time mentally doesn't make you "unstable".
Over 90% of depressive adults function perfectly allright in a society. Also the fact that he's this open and honest about it shows he has great courage and resilience.
Fortunately most people nowadays won't see it the way you see it, and because of that the world has become a better and safer place.
It seems like you attach a heavier load to the word 'unstable' than I do. Fair enough, maybe I could/should have phrased it differently. I have great respect for (young) people struggling mentally. I wouldn't like to be a 16yo in this age.
All I am saying is that I don't think it's an advantage to be so open about it in public, especially in this early stage of his career,
purely from a career perspective. Some teams might be more reluctant to hire him at some point, if let's say, he has to compete with an equally capable rider for the last spots on a team. If he becomes really good, that won't be an issue of course, since teams will take him for his (potential) results.
