Tuition
Are they all paying tuition to that Catholic school, except for Sam on scholarship? Even JJ must not have been on football scholarship since that didn't even come up when he briefly quit the team.
And JJ's football teammate whose father said he would end up in jail or in the Army - why would his family bother paying private school tuition for him?
Or do they get tuition free for going to that church?
I'm just 2/3 of the way through Season 1 on DVD so pardon me if the explanation comes out later on.
