Doing some bubble math here:
The following 29 teams are absolute locks for the NCAAs, even with a conference tournament loss:
ACC: ND, Louisville, NC State, Miami, Syracuse, Florida St
SEC: Miss St, South Carolina, Texas A&M, Missouri, Kentucky
Big 12: Baylor, Iowa St, Texas
Big Ten: Iowa, Maryland, Rutgers
Pac-12: Oregon, Stanford, Oregon St, Arizona St, UCLA
Others: UConn, Marquette, Gonzaga, Drake, S. Dakota, S. Dakota St, Central Michigan
The following 9 teams are highly probable at-large teams (would be very hard to justify leaving them out):
ACC: Clemson, North Carolina
SEC: Auburn
Big 12: Kansas St
Big Ten: Michigan, Michigan St
Pac-12: Cal
Others: DePaul, BYU
The following 11 teams I would classify as possible at-large teams (assuming a conference tournament loss):
ACC: Virginia Tech
SEC: Tennessee
Big 12: West Virginia, TCU
Big Ten: Indiana
Pac-12: USC
Others: UCF, Buffalo, Ohio, Butler, Miami (OH)
If there are no "bid stealers" in conferences like the SEC, Pac-12, MAC, WCC, MVC, Summit or (god forbid) AAC, then if my math is right there will be 5 final at-large bids that will almost certainly come from this group of 11 teams. (Of course, every "bid theft" will cause that number to shrink.)
(If someone other than Rice wins C-USA, Rice becomes a "possible" team, but frankly I wouldn't like their chances.)
