March Madness Sweet 16 Betting Trends
Just because your bracket has busted, doesn’t mean that you can’t win big during March Madness.
There have been a few trends that have been sticking out in the NCAA Tournament over the last few seasons. During March Madness, the Sweet 16 is the time where the top teams start to separate themselves from the pack, which often leads to lower scoring games.
Since 2019, sharp bettors have been profiting by taking the under, which has cashed in 11 of the last 16 March Madness Sweet Sixteen games. Underdogs have also performed well, especially against the spread, which should give bettors a good chance of making some money over the next two rounds.
