First Round March Madness Betting Numbers

March Madness betting in the first round is probably the most exciting part of the NCAA Tournament.

There are 64 teams to consider as you make a March Madness bet.  The teams are seeded 1 through 16 in each of the four regions.

March Madness betting numbers have seen the #1 seeds win every time against the #16 seeds. The average margin of victory is 25.4 points per game so the #1 seed doesn’t always cover the spread for those making a March Madness bet.

The #2 seeds have won 96% of their games against the #15 seeds.  The average margin of victory is 16.8 points per game.  Once in a great while a #15 team pulls off the March Madness betting shocker but it hasn’t happened in nine years.

The #3 seeds win 85% of the time in their March Madness betting matchups against the #14 seeds.  In the history of the tournament there have been 15 upsets.  The average margin of victory in these 3-15 games is 11.4 points per game.  #3 seeds lost in 2005 and in 2006 when Kansas and Iowa were upset in March Madness betting.

#4 seeds do almost as well as the #3 seeds for those making a March Madness bet, winning 79% of the time.  They win by an average of 9.3 points per game.  Last year Cleveland State was a winner as a #13 seed while two #13 seeds won in 2008.

The first round matchup that gets all of the attention in terms of upsets in March Madness betting is the #5 vs. the #12.  The #5 seed wins only 66% of the time and the average margin of victory is just 4.8 points per game. In the past nine years, five seeds are just 20-16 against the twelve seeds.

Six seeds actually have a better winning percentage than the five seeds in March Madness betting. They have won 69% of the time with an average margin of victor at 4.3 points per game.  Recently though the six seeds are 20-8 in the last seven years.

The #7 seeds have actually done pretty well, winning 62% of the time with an average margin of victory at 2.7 points per game.  Last year though they lost three of the four for those making a March Madness bet.

The #8 vs. #9 game is very even with the #9 seeds actually holding the 54% edge.
