Major Conference Tournament Betting Trends

Hopefully you picked up the Conference Tournament Tendencies article focusing in on the leagues that started their tourney’s last week, as some of the trends uncovered really fared well, especially those dealing with totals. In that piece, I covered the smaller conferences. Here, I am back to address all of the action occurring this week, including the major conferences like the Big East, ACC, Big Ten, Big 12, Pac 10 and SEC. Many bettors find the action this week to be even more exciting, or if you want to say, maddening, than the first days of the NCAA tournament. There will certainly be a lot to choose from, both at your sportsbook and on your TV. Make sure you consider the following trends before making your commitments.

Big East Conference

In Tuesday/Wednesday Big East Conference Tournament action, or the early rounds, FAVORITES are on a run of 17-5 SU & 14-8 ATS (63.5%) since ’05. When broken down among line ranges, you’ll find FAVORITES of less than 7-points are on a 9-2 SU & ATS run.
The quarterfinal round of the Big East tournament has been very high scoring over the last four years, with 11 of 16 games (68.8%) going OVER the total.

On average, one of every four Big East quarterfinal games is an upset, with 12 underdogs winning outright over the L12 years. Underdogs of 7-points or more during that span hold a 10-6 ATS edge (62.5%).

Underdogs have held the edge in the Big East semifinal round over the last five years, going 6-4 SU & 7-3 ATS (70%). Those getting more than 3-points have covered five of the L6 (83.3%).

Fatigue tends to set in this round as well, as defense rules the day. Since ’99, UNDER the total is 15-7 (68.2%).

A strange pattern has developed in the Big East tournament title game, with underdogs and favorites alternating ATS wins EVERY YEAR since ’98. Accordingly, the UNDERDOG is scheduled to cover in ’10 after Louisville’s chalk win over Syracuse last spring.

Atlantic 10 Conference

UNDERDOGS have managed to split the eight first round Atlantic 10 tournament games of the last two years after FAVORITES had been on an incredible 24-2 SU & 21-5 ATS (80.8%) run.

FAVORITES of 7-points or less are on a run of 18-4 SU & 17-5 ATS (77.3%) in first round Atlantic 10 tournament action since ’01.

Including 3-1 ATS a year ago, FAVORITES in the quarterfinal round of the A-10 tourney, going 20-7 SU & 18-9 ATS (66.7%) since ’03. During that stretch, DOUBLE-DIGIT FAVORITES are 9-0 SU & 7-2 ATS (77.8%).

The semifinal round of the A-10 tournament has proven quite competitive, with UNDERDOGS of 4.5-points or more having gone 5-3 SU & 7-1 ATS over the last dozen years.
The A-10 title game has been anything but competitive, with underdogs having won just once in the last 10 years (1-8 ATS 11.1%).

Big 12 Conference
There might be no other major conference tournament that has seen more UNDERDOGS cover with regularity than the Big 12. In fact, since 2000, dogs are 61-44 ATS, a solid 58.1%. UNDERDOGS of 6-points or more are 37-21 ATS (63.8%) during that stretch.

The last three Big 12 tournaments have been particularly defensive-oriented, with UNDER the total converting in 22 of 33 games (66.7%), and the losing team being held to 60 points or less in 17 of those contests.

On Big 12 tournament games with totals set at 147-points or higher, the UNDER is 13-3 (81.3%).

The last 12 Big 12 tournament quarterfinal games have gone UNDER the total (100%). UNDERDOGS are 7-3-2 ATS (70%) in that span.

Like clockwork, the last seven years of Big 12 semifinal games have seen one favorite cover, one underdog. Of the games with lines set at 6-points or higher, UNDERDOGS are 5-1 ATS (83.3%).

Conference-USA

The millennium also saw a shift from favorites to underdogs holding the edge in Conference USA, as dogs are a healthy 60-45 ATS (57.1%) since ’00.

Double-digit lines are a regular occurrence in the C-USA tourney, and teams laying 10-points or more are 19-0 SU & 11-8 ATS (57.9%) since ’06.

The best value on C-USA tourney UNDERDOGS comes with those getting 6.5-points or less, as they are 20-17 SU & 26-10-1 ATS (72.2%) dating back to ’03.

C-USA UNDERDOGS in the FIRST ROUND own a 24-13-2 ATS (64.9%) record since ’00.
Of the 16 C-USA round one matchups since ’06, the UNDER is 13-3 (81.3%).

The C-USA quarterfinal round also “goes to the dogs”, as UNDERDOGS are 9-3 ATS (75%) over the last three seasons.

With Memphis dominating the proceedings, the FAVORITES turn the tables in the semifinal round, having gone 17-3 SU & 12-8 ATS (60%) over the L10 years. The Tigers have won four straight title games as favorites as well, going 3-1 ATS (75%).

Since 2006, UNDER the total is 10-2 (83.3%) in the C-USA semifinal & final games.

Mountain West Conference

Having held the yearly edge in every one of the last eight Mountain West tournaments except 2005, UNDERDOGS are 40-18 ATS (68.9%) overall during that span.

There is a sizeable break at one particular line point in past Mountain West Tournament games. FAVORITES of 9-points or more are 8-7 ATS (53.3%) since ’02. UNDERDOGS of 8.5-points or less are an incredible 33-10 ATS (76.7%).

UNDERDOGS hold a particularly strong edge in the early Mountain West Tournament action, going 16-4 ATS (80%) in the round one and quarterfinals games since ’06.

FAVORITES have done well late in the last three MWC tourney’s, going 7-1 SU & ATS (87.5%) over the last three years in the semi’s and title games. Note: last year’s championship game was a pick em’ pointspread.

Pac 10 Conference

The Pac 10 is one of the few conferences whose tournaments have been ruled by FAVORITES in recent years, as those teams laying the points are 23-10 ATS (69.7%) over the last four years, including the first six games of the ’09 proceedings.

The Pac 10 tourney games have also been high scoring over the L4 years, 23-12-1 OVER (65.7%) since ’06.

FAVORITES of -3 to -6 points are on a run of 12-0 SU & 9-2-1 ATS in the Pac 10 Tournament.
Don’t even bother considering underdogs in the first round or quarterfinals of the Pac 10 tourney if basing it on recent years, as FAVORITES are on an incredible surge of 20-4 SU & 19-5 ATS (79.2%) in those rounds since ’06.

UNDERDOGS stand a much better chance of covering late in the Pac 10 Tournament, 11-7-1 ATS (61.1%) since ’03 in the semi’s and title games.

The key benchmark on wagering totals in the Pac 10 tourney is 156. In games with posted numbers less than that, the OVER is 34-19 (64.2%) since inception. In those higher than 156, the UNDER is 7-2 (77.8%).

Big West Conference
The Big West Conference has seen a fairly even distribution of favorites and underdog covers over the last seven seasons, with FAVORITES owning a slight 25-22 ATS (53.2%) edge.

More on the competitiveness of the Big West tourney…since ’03, there have been only 10 games with lines of 7.5-points or more, with UNDERDOGS going just 1-9 SU, but 8-2 ATS (80%) in those contests.

The last five years of the Big West Tournament have been a goldmine for UNDER bettors, as those playing that side of the total have gone 25-9, for 73.5%. During that span, on totals averaging 137.6 PPG, the games have produced just 133.5 PPG.

Big Sky Conference
The Big Sky Conference has shown a shift to FAVORITES in the last three seasons, as those teams laying points have converted 10 of the 15 (66.7%) games during that stretch.

There have only been two upsets in the Big Sky Conference tournament semifinals over the last seven years, and FAVORITES are 10-4 ATS (71.4%) in that span.

The Big Sky Conference is one of few where LARGE UNDERDOGS, or those getting 7-points or more, have a good shot at an upset, owning a 4-8 SU & 8-4 ATS record since ’98, including 2-2 SU & 4-0 ATS over the L2 years.

FAVORITES in the -4 to -6.5-point line range have been nearly automatic in Big Sky Conference tournament action, 16-1 SU & 15-2 ATS (88.2%).

Big Ten Conference
For being a dog-dominated event for most of its early years, there has been a shift to FAVORITES in the last three Big Ten Tournaments, 18-12 ATS (60%) since ’07.

There has also been a huge shift in oddsmakers’ perception on totals. Between ’99 & ’06, the average posted total in Big Ten tourney games was 130.5. Since then, it has dropped nine points to 121.5. Still, UNDER has been the correct choice in 18 of 30 games during that span (60%).

FAVORITES swept all three opening round games of the Big Ten tourney last year, both SU & ATS, slowing a run of 14-4 ATS by dogs.

Similarly, FAVORITES own a 5-1 SU & 4-2 ATS mark in the semifinals of the L3 Big Ten tourney’s after going just 1-11 ATS prior.

DOUBLE-DIGIT Big Ten tourney UNDERDOGS are 7-1 ATS (87.5%) since ’05.

LOWER SEEDED FAVORITES boast an 11-5 SU & 9-6-1 ATS (60%) record since ’98 in the Big Ten Tournament.

Atlantic Coast Conference
ACC UNDERDOGS swept the quarterfinal & semifinal games of 2009 against the spread and boast an overall mark of 44-23-3 ATS (65.7%) since ’03.

UNDERDOGS of 9-points or more are 18-6-1 ATS (75%) in the ACC Tournament since ’03, including five straight covers.

How about giving some thought to UNDERDOGS on the pointspread and money line in the opening round of this year’s ACC tourney, as they are 13-6 SU & ATS (68.4%) since ’05.

Quarterfinal UNDERDOGS are effective against the spread, but that’s it, boasting a record of 7-21 SU & 18-9-1 ATS (66.7%) since ’03.

Semifinal UNDERDOGS are even better than previous rounds, 15-6-1 ATS (71.4%) since ’99.
It’s not until the ACC title game where FAVORITES take over, 10-1 SU & 6-3-2 ATS (66.7%) since ’99.

The only recognizable trend I could uncover on totals in the ACC tourney came on games with posted numbers 150 points or higher, 10-5 OVER (66.7%) in the L15.

Mid-American Conference

FAVORITES are the preferred betting choice in MAC tournament games in recent years, with a record of 40-26 ATS (60.6%) over the L6 seasons.

The MAC title game has seen the FAVORITE go 9-3 SU & ATS (75%) since its inception. The straight up winner is 12-0 ATS.

Semifinal FAVORITES in the MAC tournament have swept the last three years of action and are 5-1 ATS (83%) in that span.

The best spot for playing UNDERDOGS in the MAC tournament has proven to be in games when the lines are 3-points or less. In such cases, they are 23-16 ATS (59%) since ’98.

OVER the total has been the preferred choice on that wagering option since ’04, with a 37-24 (60.7%) record since ’04.

Southeastern Conference
The 2008 SEC Tournament was dominated by dogs, 7-4 SU & 9-2 ATS, but split down the middle last year, 5-5-1. Overall, since ’05, dogs own a 29-25-1 ATS (53.7%) edge.

Georgia became the first SEC tourney DOUBLE-DIGIT dog to pull an upset since prior to ’98 when it beat Mississippi State in ’08. Overall, those teams are 1-15 SU & 5-11 ATS (31.3%) in that span.

In past SEC games with pointspreads less than 3-points, UNDERDOGS are 15-13 SU & 16-11-1 ATS (59.3%) since ’98.

Although it’s fluctuated back-and-forth in the last few seasons, FAVORITES own a 22-11 ATS edge in opening round SEC tourney action since ’00. Lower-seeded chalk is 5-1 SU & ATS of those games.

UNDERDOGS have been the preferred choice of bettors in SEC quarterfinals over the L3 seasons, 8-3 ATS (72.7%).

In the last nine SEC Tournament championship games, the UNDER is 8-1 (88.9%), and the UNDERDOGS are 4-5 SU & 5-3-1 ATS (62.5%).

Western Athletic Conference
UNDERDOGS covered all but one game in the 2009 WAC Tournament, increasing their four-year record to 20-9 ATS (69%). That span has also seen OVER the total go 21-10 (67.7%).

Lines of less than 3-points should raise an immediate red-flag for WAC tourney bettors, as UNDERDOGS of 2.5-points or less are a profit-making 13-5 SU & 13-4-1 ATS (76.5%) since ’00.

Although there is no first round in this year’s WAC tourney, since ’06, UNDERDOGS in the first round and quarterfinals combined have gone 14-5 ATS (73.7%) over the L4 seasons.

The WAC quarterfinals have produced 14 OVER’s, 6 UNDER’s (70%) over the last five seasons. Similarly, eight of the L10 (80%) WAC semifinal contests have gone OVER the posted total.

Amazingly, in that same stretch, all five WAC title games exceeded the total as well. If you’re combining those numbers, it’s 27-8 (77.1%) OVER for the last five years.

Enjoy the action this week everyone, and be sure to check back next week for the key information you’ll need to sort out the NCAA, NIT, CBI, and CIT brackets!
