I think it could be that the school has a program they are interested in. I think it could be a buddy they have is playing on the team. I think it could be that they grew up as fans of the team.
I don't think you can say that for every player it is just the church affiliation. And I don't think you can say that for every player it is just the coach. But I do think you can say that for certain players each of those are determining factors.
