The top four seeds in the NCAA tournament historically fare very well against seeds 13-16. The top 16 teams are 513-63 against the bottom 16 teams all-time. That’s an 89% clip. Pretty good odds.
But if you’re betting against the spread (ATS) on those top teams, it’s not as easy as just penciling in the No. 1 seeds of the world, especially when spreads are eclipsing 20 points.
So how do seeds 1 through 4 fare ATS? There’s a large disparity between the top teams from a season-long betting perspective that you should be aware of before blindly betting on double-digit lines.
