If we beat Purdue, we’re the 7 seed unless USC beats UCLA (or Wisconsin loses twice). As the 7, we would play Saturday’s IU/OSU loser in the first round at 6:30 EST on Thursday night.
If we lose to Purdue, we’re the 8 seed unless Oregon loses to Washington. As the 8, we would play the IU/OSU winner at noon EST on Thursday afternoon.
In other words, absent something weird happening, we’re playing OSU or IU in Indy, both bubble teams maybe playing to get in.
