Saw someone tweet that they would not be able to meet in the tournament until at least the Elite Eight per NCAA rules since they will have played 3 times.ISU plays Colorado in 33 days in Boulder.
Then again in Ames in February.
ISU could then theoretically play CU a 4th time in the Big XII tourney.
Even less likely, but hypothetically possible, ISU could play CU a 5th time in the NCAA tourney. lol
