Power Six Conference Tournament Betting Trends
Last week, I introduced the first of a three-part series on key betting data for the college basketball conference tournaments. In it, I covered the 15 mid-major conferences that tipped off their tournaments between March 4th and March 9th. In the second part, I covered the 11 mid-major conferences starting their tournaments a bit later, specifically March 12th or beyond. We’ve reached the conclusion of the series, as this piece will cover the Power Six conference tournaments that will commence on Tuesday, March 12th or later. These are the big boys, the tournaments that command 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.
One final reminder from the first two parts of the series, bettors should 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, conference tournament favorites off a bye were 621-193 SU and 394-338-17 ATS (53.8%) over the last 10 seasons heading into 2024 action 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.
In this piece, the power conference leagues I cover are:
ACC – March 12
BIG 12 – March 12
BIG EAST – March 13
BIG TEN – March 13
PAC 12 – March 13
SEC – March 13
