I played rep basketball and on my first Youth League team when I was 18, I was clearly better than most of the players on our team (which was shit), but the coach never played me because he had his favourites...
I'd travel to Maitland, Newcastle, Wollongong, Gosford, Hills etc and all over Sydney on the weekends, train twice a week with the team and almost never get minutes. Even in blowouts. I don't know why he picked me on the team but I never complained and kept working my ass off.
As much as I hated that coach, I still learnt a lot from him tactically and worked ten times harder to prove him wrong because I had a massive chip on my shoulder.
The next season we had a new coach. I went from never playing the year before, to starting and being the captain and had a good season..
If the above happened to a kid now, they'd switch teams, complain about the coach, or just give up. They don't have the mental strength and determination we did, that's for sure..
