Pre Season AP Rankings can predict tournament success
The following comes from a Nate Silver article in the NY Times before the 2011 tournament.
Since the tournament field expanded to 64 teams in 1985, there have been 41 cases in which a school that was unranked to start the season entered the tournament ranked in the A.P. top 10 (excluding a couple of cases where the team was ineligible for tournament play). These schools, as you might expect, were seeded highly: eight were No. 1 seeds and another 17 were seeded No. 2.
Absolutely none of these teams have made the Final Four, however: they are 0-for-41. Instead, they have been the victims of some notorious upsets, like the No. 2-seeded South Carolina Gamecocks losing — by 13 points! — to the No. 15 seed Coppin State in the opening round of the 1997 tournament, and the No. 3 seed Wisconsin Badgers being one of Davidson’s victims in 2008. Three of the No. 1 seeds that fit this description — Michigan in 1985, St. John’s in 1986, and Cincinnati in 2002 — lost in the Round of 32.
This has held up since then.
2011 Notre Dame (2) lost in 2nd round to Florida
2012 Florida State (3) lost in 2nd round to Cincinnati
2013 Georgetown (2) lost in 1st round to Florida GC
2013 Miami (2) lost in 3rd round to Marquette
2014 Villanova (1) lost in 2nd round to Uconn
2014 Iowa St (3) lost in 3rd round to Uconn
2015 Maryland(4) lost in 3rd round to Kentucky
2015 N. Iowa (5) lost in 3rd round to Louisville
