Here is how I see it:
SMU is one of the last teams in the dance, and is almost definitely playing in Dayton. I have SMU ahead of Iowa at the very bottom of the bubble, with both squeaking in. I have an empty slot for my last team for right now (more on that later).
5 bubble teams are still playing and need to win to go to the dance:
Tennessee over South Carolina
Providence over Seton Hall
Florida State over Virginia
Minnesota over Wisconsin
Missouri over Florida
I put them in order of likeliness of a win. Tennessee and Providence just need to avoid bad losses, and Tennessee may even be able to survive a bad loss. The other 3 teams' resumes are not as strong as SMU's right now, and a "good" loss isn't going to help them. If any of FSU, Minnesota or Missouri win, SMU moves down a slot, and may drop out altogether. I don't think any of those schools are going to win, but SMU will be sweating it out today.
St. Joe's is near the cusp, but I don't think a loss to Dayton hurts them enough to drop them out. Dayton is safely in the tournament.
Iowa - Bubble Watch and Lunardi still have them safely in the dance, I think they are the second to last team in right now.
Lunardi annoys me because he has so many mistakes. For example, his bids by conference for the Big East and Pac 12 do not tie out to his bracket. He lists Arkansas in his "Next Four Out" but then has them in his bracket. It is very sloppy for a journalist to be making those mistakes.
Since Lunardi doesn't have a last team in the dance, neither do I. I suspect one of the FSU, Minn, Mizzou teams will pull the upset and take a bid. If they all lose, maybe there is a spot for Southern Miss or Toledo.
