I think Pitt would benefit the Big Ten better than 'Cuse or Rutgers.... But I DOUBT the Big East would lose more teams without a MAJOR fight.
Iowa State is always a worry for us. Usually, playing us is their bowl game... and they do play well against us. We don't take anybody too lightly.
The Big Easy may have their hands full just surviving on down the road. They have few big State schools to carry the load, few big stadiums, etc. It will be interesting to watch who woos who over the next few years.
