I was going through some stuff to put a potential preliminary bracket
together. As it is, I'm finding really only about 39-41 teams worthy of the 37 at large spots. So the bubble appears to be really soft again. I think 20-11 would get IU a bid at this point (not sure yet of what seed).
Right now, I'd say the last four in are OSU, MIA, BYU and MISS (yes, MIA has the win over Dook, but also a horrid loss at home to Eastern Kentucky and their schedule like ours was relatively soft). First four out would be ALA, WASH, TENN and DAV.
