FFQF Home Team – LA Rams
On game day, the Patriots will be considered the away team, and will suit up in the away team’s locker room. That’s because the NFL rotates between the NFC and the AFC each year. Last year, the Patriots were the home team at U.S. Bank Stadium in Minnesota.
This means the Rams will be the home team.
