Historical March Madness Trends

Historical outcomes underscore why March Madness remains difficult to predict, even among top-ranked teams:

• Of the 20 teams to enter the tournament undefeated, only seven have won the national championship
• Just 13 teams have successfully defended a national title
• UCLA holds the most NCAA championships (11), though the program has not won since 1995
• Since regional seeding began in 1979, No. 1 seeds have won 59.6% of national championships

These trends illustrate why tournament performance often diverges from regular-season expectations.
