Joe Lunardi is really not very good at predicting seeding. He is good a predicting which teams will be in and which will be out, which really isn't as hard as you think. I have a hard time believing we are still a 3 seed if selection sunday were today. I would bet money on a 4.
The encouraging thing is that about half the bracket makers still have ISU as a 3 which means it is certainly on the table. Every power 5 team except for five of them has a loss left on their schedule thanks to conference tournaments. To be honest, I can't say I'd rather have a 3 over a 4 without looking at the bracket either.
