If you are looking to do some of your own data analysis, Sports Insights’ historical databases are a great place to start. We offer downloadable databases for the NFL, MLB, NBA, NHL, WNBA, college football, and college basketball.
Our archived data goes back to 2003, and once downloaded, you can manipulate the data however you see fit. The database includes the opening and closing lines for both the spread (or moneyline for MLB and NHL) and the over/under. It also includes the date, NSS number, final scores, as well as Sports Insights’ proprietary betting percentages.
