This year's Sweet 16 features no mid-majors — a first since the bracket expanded to 64 teams in 1985 — with the SEC (a record-seven teams) and Big Ten (four) dominating the field. There are only four conferences with teams playing in the round and that's the fewest in NCAA Tournament history.

Madness continues on Thursday with four Sweet 16 games, including No. 1 seed Duke and Cooper Flagg facing No. 4 Arizona.
