Give it some time, its going to occur. I would say that the athletes in the non-revenue sports will sue the collective to get their "equal share" of the revenue.
When the school is sharing their data base of season ticket holders, and providing that information to the collective, then it's difficult to say that that the school and the collective are separate parties. Why would the EIU athletic department refuse to give the season ticket holders list to the collective if they were not concerned about Title IX problems in the future, like they have had in the past?
This is America, you can sue anyone, that does not mean you are going to win the case but does EIU want to have another public relation problem over woman's sports and the Olympic sports, their actions today, says they are not willing to fight that fight.
