With this final piece covering the Power 5 conferences in college basketball, I wrap up my three-part series covering some of the key betting trends available for each of the conference tournaments. The Power 5 conference tourneys will commence on Tuesday, March 10th or later. These are the big ones, the tournaments that grab the biggest audiences, and hence the most attention from bettors. These leagues also have the most teams in the running for the NCAA tournament top seeds, as well as most teams on the bubble, so the stakes are always heightened.

Bettors need to understand the value of having a bye in conference tournaments is typically significant, especially when they are believed to be the better team. In fact, heading into the 2026 action, conference tournament favorites off a bye were 394-121 SU and 274-233 ATS (54%) over the last six seasons against teams that played earlier in that tournament. That is a winning wager without anything else considered. Remember that when you try to project chances for upsets earlier in these tournaments, especially if you are led to believe the underdog may have picked up momentum from beating a lesser team in a “play-in” type of game. 

Besides that, in search of other prominent systems for readers to take advantage of, I was able to uncover two incredible systems that have developed in recent years of conference tournament action regarding extreme scoring totals from the prior game’s win. They read as follows: 

1.  Conference tournament favorites coming off a tourney win scoring 90 points or more are on an incredible 73-16 SU and 64-24-1 ATS (72.7%) run dating back to 2017!

2. Conference tournament underdogs coming off a tourney win allowing 55 points or fewer are on a brutal 29-92 SU and 43-77 ATS (35.8%) skid dating back to 2020! 

Note: All of these betting systems included games heading into the respective 2026 tournaments.

·  Only three of the last 25 Big East quarterfinal teams that enjoyed a round 1 bye have lost to a team that played, going 16-9 ATS (64%).

·  Big East tourney favorites in the -5 to -9.5 range have been vulnerable, 25-13 SU but 13-25 ATS (34.2%) over the last 12 seasons, although they did go 2-0 SU and ATS last year.

·  Teams that are off a bye in the Big Ten tournament are 25-14 SU but 13-28-2 ATS (31.7%) versus teams that already played since 2018. This makes it one of the few leagues where having a bye hasn’t proven all that beneficial.

· The Big Ten tournament semifinals are 12-4 Over the total (75%) since 2017, including Overs in the last eight.

· Big Ten tourney conference title game favorites are currently on a 4-5 SU and 2-7 ATS (25%) skid, including Wisconsin’s (-4.5) 59-53 loss to Michigan in 2025.

SEC

·  Lines of 7 points or more should be noted for two reasons in the SEC tourney. First off, favorites in these games are on a 37-8 SU and 27-16-2 ATS (62.8%) run since 2014, and second, these games have gone Under the total at a 30-14-1 (68.2%) rate.
