I don't think this is as much of a lock as you might think. If Indiana doesn't win @Michigan and/or doesn't win the B10 tournament, I could see KU sneaking in there
I am not saying it's a lock but the NCAA will do everything in its power to get IU to Indy. If IU slides further then it may not happen but if they are anywhere close to being a #1 seed then they're going to Indy.
