I don't see this so much as a church and state issue as a question of appropriateness. Why does a religious representative belong on the staff of a sports team? Even if he's unofficial and unpaid, to me it's still an intrusion of religion in a place where it doesn't belong. Why can't they just put a sign up in the locker room: "The UNIVERSITY Chaplain is available to any students who desire counseling. Phone number: Office location:"
