Thanks for your patience Jeremy. Could #7 mean ISU has offered one of the two surprises and so the other is pulling out to save face (which I think typically happens?)
The way I would look at the two unnamed is this... No offer has been made to them, but both parties informally know what the magic range would need to be to make conversations worth-while, and neither side has walked away (except for possibly 1 of the 2 candidates late today).
