Decided to do some research on what day of the first round has more upsets, and what time of day.
2015: #3 Baylor (Morning, Thurs), #3 Iowa State (Morning, Thurs)
2014: #3 Duke (Morning, Fri)
2013: #2 Georgetown (Afternoon, Fri), #3 New Mexico (Night, Thurs), #4 Kansas State (Day, Fri)
2012: #2 Duke (Afternoon, Fri), #2 Missouri (Day, Fri), #4 Michigan (Night, Fri)
2011: #4 Louisville (Day, Thurs)
2010: #3, Georgetown (Night, Thurs), #4 Vandy (Day, Thurs)
2009: #4 Wake Forest (Night, Fri)
2008: #4 Vandy (Night, Fri), #4 UCONN (Day, Fri)
2007: NONE
2006: #3 Iowa (Day, Fri), #4 Kansas (Night, Fri)
2005: #3 Kansas (Night, Fri), #4 Syracuse (Night, Fri)
2004: NONE
2003: #4 Dayton (Night, Thurs)
2002: #4 USC (Night, Thurs)
2001: #2 Iowa State (Thurs), #4 Indiana (Thurs), #4 Oklahoma (Fri)
2000: NONE
24 in 16 years (so far). 10 Thursday, 14 Friday
13 of 19 on Friday since 2004 (68.4%)
No 2 seed lost from 2002-2011 (10 years) and only three 3 seeds lost during that time.
A top 4 seed only lost 15 times in the first 12 years of this millennium. 9 have lost in the last 4. So all the upsets the last 4 years shows how crazy the tournament has become.
