The trend continues.
Home favorites were just 31-42 against the spread entering Week 9 of the NFL season, and then they went 2-8 to bring that record to a ridiculous 33-50. Home teams in general are just 65-70 straight-up this season, which indicates 2020 might not have been an aberration when home squads went 127-128-1.
Turns out, full stadiums haven't corrected that.
It's something to keep in mind, whether you want to ride the trend or fade it with the assumption that home-field advantage will eventually be restored, with added value for those riding home teams.
