This divisional matchup fits a historically profitable betting system developed by the Action Network that reports a return on investment (ROI) of 10%.

If you had bet $100 on each game that has fit this betting trend since 2005, you’d be up about $14,000. That’s roughly $800 per year.

And this is over a massive sample size: 1,400+ games over the last 17 odd seasons.

The betting system incorporates public tracking data also proprietary to the Action Network. The philosophy behind the algorithm is simple: fade the retail bettors on unpopular teams.

This system’s 10% return on investment is better than the average annual return of the S&P 500, which has hovered at around 8% for over a century. That index is down over 13% year-to-date. Meanwhile, Bitcoin, for instance, is down about 50% during that same timeframe.

Still, don’t use this betting algorithm as an alternative to investing. The aforementioned figures are purely for reference.
