You never know. Maybe Wiscy's strong showing against OSU somehow changes how you ranked PSU, Minny and Mich. but probably not. If before you had Mich ahead of Minny, or Minny ahead of Mich, you are probably not going to change it.
But you could argue for the sake of consistency, we should vote. After all if Wiscy had won, we would be voting.
Plus what am I supposed to do on a Sunday morning if I am not submitting my power rankings?
