The bad feeling comes from the fact we've seen this movie plenty of times before.
I started a thread myself probably for the purpose of hoping to read something that would relieve my anxiety a bit. Lol. The reality is the BTT is wildly unpredictable. The reality is even though Indiana was in a funk at the end of the season they still are the same group of guys who beat Kansas, what seems like eons ago; but of course, they are also the same group of guys who lost to IUPUI (or whatever school, and yes, Iowa had Omaha, so there's that). Also, it's Tom Crean creepin' the sidelines, so that should add a few points in Iowa's favor based on incompetence alone.
Still, you're right, Indiana is/can be explosive. And Iowa has perfected the art of laying an egg in the BTT. All of that said, did anyone really think two weeks ago that we would even be biting our nails at the prospect of Iowa getting an at large bid? I sure didn't. So some perspective might help. Even if Iowa loses tomorrow, this season has already surpassed my expectations (at least as far as the conference regular season is concerned).
Plus, should Iowa lose, they will then be in the NIT and getting invaluable experience from that. Either way, plenty to be grateful and appreciative of.
