Who said anything about quotas? And while you are right that coaching and playing are not the same, the latter is at least something of a proxy for qualifications of the former that is better than mere general population. I’m just saying you would in fact expect more.It still equals a quota system for 1 group. Maybe there are only 6% qualified for coaching. There are different skill sets for playing and for coaching. Too much complaining and crying about being picked on. Not all good students are meant to be teachers.
now, the key question is if you’d expect more, why don’t you get more? That can be intentional, a result of a neutral exclusionary policy, or pure coincidence.
