Seed Distributions for March Madness 2017: A Tool for Bracketologists

Round of 64 Upsets

In 28 of the past 32 tournaments (1985 through 2016), one or more teams seeded 13, 14 or 15 have won a game in the Round of 64. Our research on causal inference using observational data ([1],[2]) has been adapted to look at key statistics that may predict upsets for these seeds. From 2003 through 2016, we used the Balance Optimization Subset Selection model (BOSS) to select two teams each year. Of the resulting 28 teams selected (out of a possible 168 teams that could have been selected), 10 ended up being upsets. During this time period, there were a total of 23 upsets. Below is a table, constructed using the BOSS model, which contains the two teams selected each years (from 2003 to 2016) that share the characteristics of previous upsets. We also report the actual upsets that occurred during this time period.

Year Upsets Chosen by BOSS Actual Upsets
2003 (13)Tulsa, (14)Troy (13)Tulsa
2004 (13)UI-Chicago, (13)Texas - El Paso None
2005 (13)Vermont, (14)Niagara (13)Vermont, (14)Bucknell
2006 (13)Bradley, (14)Xavier (13)Bradley, (14)Northwestern State
2007 (13)Albany, (13)Holy Cross None
2008 (13)Sienna, (13)Oral Roberts (13)Siena, (13)San Diego
2009 (13)Cleveland State, (13)Portland State (13)Cleveland State
2010 (14)Ohio, (15)Morgan State (13)Murray State, (14)Ohio
2011 (15)Akron, (15)LIU-Brooklyn (13)Morehead State
2012 (14)Belmont, (15)Lehigh (13)Ohio, (15)Lehigh, (15)Norfolk State
2013 (13)Lasalle, (14)Davidson (13)Lasalle, (14)Harvard, (15)FGCU
2014 (13)New Mexico State, (13)Delaware (14)Mercer
2015 (14)Georgia State, (14)UAB (14)Georgia State, (14)UAB
2016 (13)Iona, (14)Buffalo (13)Hawaii, (14)Stephen F. Austin, (15)Middle Tennesse State

Using the BOSS model, the upsets for the 2017 tournament will be available after Selection Sunday.
