My rough swag at those outside now and what they probably need to get in starting from the end of the list.
I do not see anyone beyond these teams having any shot whatsoever at an at large. They are all way too far back and you just can't build an at large resume this late with the way this committee looks at things.
UC Irvine- need to win the auto bid. If they lose the championship to UCSD, and no bids are stolen, and the rest of the bubble loses soon...i would give them a very slim chance.
Colorado State - at a minumum needs to beat Nevada and Utah State, that would get them to the final. If they lose that one to UNM or SDSU they could get in depending what others on the list do.
Boise State - similar profile now as CSU but opposite sides of the bracket, if they beat SDSU and New Mexico, they have a pretty good chance to get in, especially if the finals loss is to Utah State
Texas - Needs to beat A&M to be in the conversation. If they do and get ALOT of help, they could sneak in. Otherwise they need to beat A&M and Tennessee. That is likely enough unless there are alot of bids stolen.
Ohio State- out of the Big 10 tournament, keeping them here as they will likely be listed as a first 4 out but there is not a realistic path
UNC - Needs to beat Wake and Duke to get to the final. Do that and they are in. If they just beat Wake and then lose to Duke they could possibly sneak in with help of no bid thieves
Dayton - Almost certainly need the auto bid as they wont get any good wins on their path. If they lose a close one to VCU in the final and they get ALOT of help there is a slim shot.
--------------------
Wake- basically identical path as UNC. i give them a slightly better chance to sneak in if they beat UNC and then lose to Duke.
VCU - basically identical chance as Dayton, if then get to the final and then lose a close one to Dayton, they have a slightly higher chance to sneak in than Dayton would vice versa.
Xavier - Possible to get in even if they lose to Marquette if they get tons of help (everyone below them loses quick and only 1 or less bid stolen. Beat Marquette and they have much more breathing room for not needing help but they wont fully punch their ticket unless they beat Marquette AND St. John's.
UCSD - The only path is to get to the final and then lose to UC Irvine, if they do that and not many bids are stolen they have a somewhat decent chance ~40%
San Diego State - Likely in already, win 1 to clinch it. if they lose and their are bids stolen they are in danger
Vandy - a bit of a nervous wait until Selection Sunday, should be ok unless there are bids stolen Dayton a real possibility
Indiana - Win against Oregon to lock themselves in. If they lose they slip behind Vandy and are vulnerable to bids disappearing.
Everyone above these teams should be fine although Arkansas, WV, OU, Utah State, Baylor, Uga, New Mexico would all be in play for Dayton depending how the next couple days go.
