NCAA basketball: Conference tournament trends

228

March Madness is more than just the NCAA Tournament. 

In Part 2 of a three-part series on conference tournament betting systems, I offer up angles for tournaments in action over the next seven days (March 2-8), with at least one 60%-or-better angle from each conference. Next week I’ll focus on the remaining tournaments.

 

These angles focus on three key areas: byes, rounds and line ranges. As a general thought, bettors should understand that byes in conference tournaments are statistically significant, especially when the team on a bye is believed to be better than its opponent. In conference tournaments, favorites with the advantage of a bye are 474-159 SU and 298-254-16 ATS (54%) over the last eight years. Remember that stat anytime you think an underdog might have picked up some momentum from beating a lesser team in a play-in round.
