Sports Stats ‘on Tapp’ is a sports statistics blog published with a focus on stats that go beyond the numbers.
The first week of the 2013 NCAA men’s Div. I basketball tournament is in the books and we have our Sweet Sixteen contingent. Three of the four number 1 seeds advanced, as did a trio of #2 seeds, three #3 seeds and a pair #4 seeds.
Three double-digit seeds remain in the tourney as #12 Oregon, #13 LaSalle and #15 Florida Gulf Coast won two games to reach the Sweet Sixteen. Three double-digit teams in the Sweet Sixteen matches the three that made the round of 16 last year.
Back in 1985, the NCAA went to a 64-team field for this tournament. Since that year, 61.9% of the teams making it to the Sweet Sixteen were teams that started the tourney as a #1, #2, #3 or #4 seed.
Another way of looking at this stat is that in the past 29 years of the tournament, 177 teams that were a #5 seed or lower made it to the Sweet Sixteen, an average of just over six teams per tournament (this year there are five teams seeded lower than a #4 seed still in the tourney).
Here’s a look at how many of each seed made it to the round of 16 in the tournament since 1985 (number of each seeds since 2010 is listed in parenthesis – total of 64 teams)
#1 seed…98 teams (13)
#2 seed…72 teams (11)
#3 seed…57 teams (8)
#4 seed…49 teams (8)
#5 seed…39 teams (3)
#6 seed…38 teams (4)
#7 seed…19 teams (1)
#8 seed…10 teams (1)
#9 seed…4 teams (2)
#10 seed…21 teams (3)
#11 seed…15 teams (4)
#12 seed…19 teams (3)
#13 seed…5 teams (2)
#14 seed…2 teams (0)
#15 seed…0 teams (1)
#16 seed…0 teams (0)
Here’s a few interesting notes about the seeds of the Sweet Sixteen teams from 1985 through 2013.
