Power conferences dominate NCAA Tournament's Sweet 16, with no upsets from mid-major teams.

For the first time since 1985, the NCAA Tournament's Sweet 16 is made up entirely of teams from power conferences. The top four seeds went undefeated in the first round, marking a chalky bracket without any upsets from mid-major teams like St. Peter's or Loyola Chicago. The SEC leads with seven teams in the Sweet 16, followed by the Big Ten, Big 12, and ACC, each with four teams. This year's Sweet 16 represents the fewest number of conferences in tournament history, highlighting the dominance of power conferences.
