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.

Only five double-digit seeds advanced over the past two days: two No. 10s, one No. 11 and two No. 12s. That ties the fewest since 2017.

Based on history alone, it's more likely than not a No. 1 seed will cut down the net at the end of the NCAA Tournament. Only one team gets to be a champion, and the number of teams capable of winning six consecutive games against the very best is small.
