I'm not sure that article is right. If FSU is in the playoff and another ACC school (can't be ND so presumably Louisville) goes to the Orange against a Big 10 school, then the ACC also gets Reliaquest and slides ND in that spot which moves every team up two slots with the next best team going to Pop Tarts.
If FSU is not in playoff and the ACC opponent in the Orange is not Big 10, then the ACC loses Reliaquest. ND or UL would go to Pop Tarts, the other to a lesser bowl than that and everyone else drops two slots.
