Selection Sunday is here, and the NCAA tournament field is nearly set. With less than 24 hours until the bracket reveal, 12 burning questions remain for the selection committee. Will Duke secure the No. 1 overall seed? Can Miami (Ohio)'s perfect season earn an at-large bid despite a weak schedule? And does Auburn have any shot at a record-breaking 16-loss bid?

Duke appears locked into the top seed after winning the ACC title, despite injuries to Caleb Foster and Patrick Ngongba II. The Blue Devils boast the nation's best résumé with 17 Quad 1 wins and a dominant NET ranking. Meanwhile, Florida seems set as the fourth No. 1 seed after its SEC semifinal loss to Vanderbilt opened the door for Houston or UConn, who both fell in their conference title games.

Bubble teams face elimination as Dayton and VCU meet in the Atlantic 10 final. The committee must decide if VCU's solid metrics outweigh its lack of quality wins. San Diego State and SMU also hang in the balance, while Auburn's 16 losses make its inclusion historically unprecedented. The Selection Show at 6 p.m. ET will answer all these questions and more.
