How do the preseason Top 25 fare in March Madness?

  unc UNC's 2009 team was the last preseason No. 1 to win the national championship.

Whoever opens the season at No. 1 in the AP poll, they might as well start planning for March now. No preseason No. 1 has ever failed to make the NCAA tournament.

Of the 25 rankings in the AP poll, the No. 1 is the only position that can claim that unblemished record. Still, of the 826 teams that have been ranked in the preseason since the NCAA tournament expanded to its modern format in 1985, 83.5 percent have made the tournament.

And if a team finds itself in the Top 5, they can feel extra safe. Of the 190 teams that have been in those positions, only 10 have failed to go dancing. And yes, those that missed out include a No. 2 (Louisville went 18-14 in 1987) and No. 3 (Kentucky went 21-12 in 2013).

But those 1-5 teams also account for 72 of the 136 1-seeds in the tournament since 1985, an average of just over two of the four every year. They’ve also accounted for 18 of the 34 national champions, though really that's just Nos. 1-4. Teams ranked No. 5 in the preseason poll have never managed to win the title in the NCAA tournament’s modern format.

On average, teams ranked in the preseason Top 5 don’t find themselves with lower than a 5 seed come tournament time, though No. 2 and No. 3 have been seeded as low as 10.

Then No. 1s? Well they had an 8-seed in 2014 (Kentucky, which went on to lose in the national championship game), but almost two thirds of all preseason No. 1s entered March Madness as a 1-seed.

So, how have they performed once the tournament starts?

Preseason No. 1s have made it to the national championship 13 times since 1985, but only six of the 34 preseason No 1s have won the title bout (though that is more than any other preseason rank). The most recent of those came in 2009, when UNC went 34-4 and beat Michigan State for the crown.

But half (17 of 34) of the preseason No. 1s have failed to make it out of their regional, losing before the Final Four, so starting the year as top dog definitely doesn't guarantee a trip to the national semifinals.

Still, it’s definitely not a bad place to be.
