I don't know, but I was told that the current schedule wasn't done until last Spring. That was in connection with a discussion about the way it's back-loaded, with all the top teams playing each other in the final month of the season. If that's true, then the schedule probably won't be set in time to do you much good.
As for Okie State, this would be an uber-classic "trap" game under ordinary circumstances. 'Pokes had a huge win over TCU last week, and play at home against Baylor and Oklahoma the next two weeks; meanwhile, ISU is 3-6 and was drubbed in its last game.
The circumstance which isn't ordinary is recent history. The coaches and probably a couple of players remember coming to Ames with a 10-0 record and national title hopes, leading by 17 in the fourth quarter, and going home with a loss. Makes it less likely OSU will be looking past this game.
