NCAA Tournament action resumes Thursday as the Sweet 16 gets underway with four huge games that each bring compelling storylines. By night's end, just 12 teams will be left standing in the race to crown a 2025 national champion.

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.
