It's not just racism - although it is extremely racist and disgusting. It's also misogynistic to presume that the player needs to get away from his partner, the ole ball n chain, in order to be a better player.
That's the part we don't know.
Maybe the young player/s did have some toxic relationships that they were dealing with and did need some kind of intervention.
As the head coach though you don't get involved in that. You get people trained in the relevant fields to assist.
Clarko is a control freak though so he'd be exactly the kind of person to think he knows it all.
