1. It's very hard to win a title.
Only 35 programs (if I counted right) have won a NCAA title, in 76 seasons.
In the first 30 years, 20 different teams won titles. Teams like CCNY, Loyola, LaSalle, San Francisco, and Holy Cross won titles. They, of course, have fallen into relative obscurity in the sport. Teams like Oregon, Wisonsin, Wyoming, Utah, and Stanford also won their only titles in the early stages of the tournament.
So over the last 46 seasons, 21 teams have won at least one title.
2. It's even harder to win a title if you are not from a power conference.
Over the last 50 years, only 5 champions have been from non-power conferences and two of those titles came from UofL, which is now in a power conference. Another was from Marquette, which is also in a power conference.
3. It's really, really hard to win if you are not an already established power, especially recently.
Of the last 20 champions, 15 were from programs that already had at least one title.
And four programs, Duke(5), UConn(4), UK(3), and UNC(3) have accounted for 15 of the last 25 titles.
And in the last 15 years, Duke(3), UConn(3), UNC(2), and UK(1) have accounted for 9 of the 15 titles.
Bottom line, it's good to be one of the top programs, your chances of winning are significantly higher every year.
Just food for thought.
