Road underdogs went 7-1 against the spread (ATS) last week and have been gangbusters over the last five seasons.
Dogs on the road are now 373-294-19 ATS since the 2018 NFL season, good for a 7% ROI and a profit of about $5,500 for $100 per game bettors.
For reference, the S&P 500 is up about 5.25% per year since 2018, if you invested using dollar cost averaging instead of a single lump sum.
Road underdogs are 15-8 ATS year-to-date for a return of $759.
