re: What would you do with a son who doesn't want to play basketball anymore?

Wanting to finish the season is the right thing to do.

Who knows maybe he'll change his mind during the season. Maybe there will be injuries or academic ineligibilities that will give him a chance.

But in the end, if his heart isn't in it there's no point in forcing him, it will just make everybody involved miserable. You can't want it for them.

But if he's not playing basketball I would insist that he find another worthwhile activity to be involved in.
