Conference tourney tendencies produce profits


One of the most popular pieces in our annual VSiN Bowl Game Betting Guide is the one on conference trends. Whether it’s matchups, motivation or perception, certain conferences generally match up well with others in certain types of games and line scenarios. Naturally, the same goes for college basketball’s postseason, the NCAA tournament. A champion from one of the power leagues is usually a national title contender, while a bubble team from that same league is a potential upset victim. A mid-major with a gaudy record is always a popular Cinderella pick but might be overhyped by bettors and oddsmakers.

I’ve determined each conference’s performance records in varied situations in recent tournament games. I’ve also listed the teams from each league that will be playing in this year’s tournament and their opening matchups. This will help you spot the best qualifying trends, line and total ranges, round level of games, results by seed number and, perhaps most importantly, how they fare against some of the other conferences.

Not unexpectedly, the Big Ten leads the way in number of teams in the field. However, the Atlantic Coast Conference and the Big 12 are well represented too. Of course, the tournament’s top seed is mid-major Gonzaga — and the favorite to take home the title in April.
