Sunday’s lineup is headlined by the SEC and Big Ten championship games. However, perhaps the most impactful result of the day will come in the A-10, where Dayton could steal a bid from the bubble teams currently listed in the field.

Check back throughout the night for more insights on the latest results.

Bubble movement

The NCAA Tournament bubble has reached its final form, with only the threat of bid-stealers left. Debate will rage on over the resumes which deserve a nod.

• SMU is perhaps the safest of the teams currently projected in the Last Four In, with consistent metrics across the board and the pending return of BJ Edwards in their favor.
• Missouri also appears safe, but must rely on bracketology to correctly predict how the Selection Committee will view their low NET ranking against what is a solid resume compared to competitors.
• VCU is currently projected in the field as an automatic bid, but if they suffer a loss against Dayton in the A-10 Championship, they should slot into the field between Missouri and SMU.
• Texas sits on the cutline entering Selection Sunday, with better Q1 results than the teams in the First Four Out. They will also have to sweat out the results in the A-10, as they are the most likely to miss the field due to a bid-stealer.
• Despite the weak overall record, Auburn does hold a real case for an NCAA Tournament bid. As the top team in the First Four Out, they must root against a bid-stealer and lean into the analytic argument which places them above teams like Texas and Missouri.
• Oklahoma, SDSU, Indiana and New Mexico all appear too far off the cutline to make it into the field at this point. The Sooners make the most compelling case of the group, finishing the season on a hot streak.
