On Thursday, I started a series qualifying the key data from my Round-by-Round and Conference Trends articles in the VSiN Bracket Mania Betting Guide, essentially taking the leg work out of the process for readers. That piece on Thursday was for the First Round. This next piece is, of course, the NCAA betting trends for the second round, and I will continue this for every successive round afterward. Hopefully, it will help you attack the tournament more successfully in 2024. Best of luck on the Saturday & Sunday games.
