March Madness: Sweet 16 Betting Trends

You are at the stage of the bracket where some teams never lose and some teams never win. Wouldn’t it be nice to know the March Madness betting tendencies of those teams over the past decade? No problem.

Underdogs have been the best bet in recent years, as they are 12-4 ATS past two tournaments in the Sweet 16. Add in 2011 and it's a 17-7 ATS streak over three years.

Three of the four No. 1 seeds remain in 2014, but they did not cover many spreads recently at this stage, going just 2-8 ATS in 10 games over the past two Madnesses (0-3 last year).

Higher-seeded teams were 5-3 last year and 6-2 in 2013 for an 11-5 SU run in the Sweet 16 round.

Check out the Sweet 16 betting trends and watch for lines (and bonus specials) at BookMaker.

Underdogs have been excellent in the past two tournaments, rolling to an 11-5 ATS record in Sweet 16 action. Oregon and Florida Gulf Coast are both double-digit underdogs after crashing the bracket as No. 12 and No. 15 seeds respectively.

But not everyone is cheering on the underdogs.

“Florida Gulf Coast is a great story as a 15 seed making the Sweet 16 and they are getting lots of positive press,” said Kevin Bradley of, who had 80 per cent of early betting on the Eagles. “Normally we are happy when underdogs cover spreads, but we are cheering for the Gators as 13-point favorites because so much of the early action is on FGCU.”

Three of the four No. 1 seeds remain, but they did not cover many spreads recently at this stage, going just 2-5 ATS in seven games over the past two Madnesses.

Bradley would like to see Oregon sent packing by No. 1 Louisville because they have a 300/1 wager on the Ducks to win the tournament.

Still, higher seeds tend to win at this stage of the competition. Higher-seeded teams were 6-2 SU a year ago but just 3-5 SU in 2011 for a two-year total of 9-7 SU.

There are two cases where 1 seeds face 4 seeds and there has been a reliable UNDER trend when that happens historically. The Under is 9-3 in the past 12 games where a No. 1 seed plays a No. 4 seed. Indiana vs Syracuse in the East and Kansas vs Michigan in the South fit the bill.

Last year, three teams seeded 10 or higher played in the Sweet 16 and all three covered the spread (NC State, Ohio, and Xavier). If that pattern holds up, Oregon as the 12 seed would cover against No. 1 Louisville in the Midwest region, Florida Gulf Coast will cover against No. 3 Florida as the first-ever 15 seed in the Round of 16, and No. 13 La Salle will upset No. 9 Wichita State in the West Region.

The East region sees the top four seeds still intact.

No trends of note


Michigan State never loses against the spread in the Sweet 16. They have been here five times since 2001 and are 5-0 ATS. They are small chalk against Louisville, a team they have only played twice since 1999 (they won and covered both times).

North Carolina is 4-1 ATS in five Sweet 16 matches. [ Read dozens of Sweet 16 props ]

Syracuse never covers the spread in the Sweet 16. They have been here four times since 2001 and are 0-4 ATS. Ohio State is 0-3 ATS in three trips.

On top of the actual bracket trends, there are some general angles and tournament-specific trends for several teams that worth exploring.

Xavier continues to be the best bet in college basketball at tournament time. With two wins last week, they are now 17-2-1 ATS in 20 tournament games this decade! They opened as 6-point underdogs against Baylor.

Indiana has won three in a row as an underdog, but overall, they have been dreadful as a big dog (they are dogged by 9 points against Kentucky). The Hoosiers are just 4-13 as dogs of 9 or more points.

Florida gets Marquette in the West and they are on an 8-2 ATS tournament run after two covers last week. But they are small underdogs here and are winless ATS the last six times in that role.

Cincinnati is riding a couple of hit trends for bettors as they are 8-point underdogs against Ohio State. The Bearcats are 8-3 ATS past 11 games as underdog and 8-1 ATS in their past 9 games overall.

NC State and Ohio also boast some tough underdog angles, ditto Louisville which is a 5-point underdog against Michigan State.
