Two years ago, it finally happened –  after 33 years and 132 straight wins, a 1-seed lost to a 16-seed!  And it wasn’t even close – UMBC beat Virginia 74-54.

You’d expect the 1-seeds to be dominant, right?  Sure they get beat plenty in the later rounds of the tournament.  Some of my most memorable games are ones where 1-seeds were upset in the second round (Bama over Stanford in 2004 and Northern Iowa over Kansas in 2010).  But…yeah.  The 1-seeds have been dominant.  They’ve won 63% of the past 35 tournaments and 7 of the last 10!

Bracket Performance History and Advice

• First Round:  A 1-seed has now only lost once in the First Round.  There have been close calls, but actually picking the upset is Bracket suicide.
• Second Round:  All 1-seeds will reach the second round, and 86% of them advance further.  It’s basically a toss up whether only 3 or all 4 will advance to the Sweet 16.
• Sweet 16:  It’s not likely that all four 1-seeds will survive past the Sweet 16 – it’s only happened 8 times.  At least two, and most likely three 1-seeds will win their Sweet 16 matchup.
• Elite 8:  1-seeds are the only ones to have at least one representative in all but two Final Fours, so at least one will probably advance.  Most likely, only one or two 1-seeds will make it past the Elite 8.
• Final 4:  1-seeds are 20-10 in Final 4 games against lower-seeded opponents.  There has been at least one 1-seed in 26 of 34 (76%) championship games.  Seven Championship games (including 2 of the last 4) were a matchup of 1-seeds.
• Final:  1-seeds have won 63% of the past 35 tournaments and 7 of the last 10!  They are 15-5 against lower-seeded opponents.

Record in the Second Round
