How many teams have started an NFL season 8-0?

Answer 1

No National Football League team has ever gone 19-0 is a season, although the 2007 Patriots' song after their perfect 16-and-0 regular season had the line "we'll come out of the season"/"19 and 0".

Three teams have gone 18-and-1:

1. the 1984 San Francisco 49ers, who lost 17-20 to the Pittsburgh Steelers in their seventh game
2. 1. It ought to be noted that, like the 1972 Dolphins, the 1984 49ers played a distinctly weak schedule, not playing:
      • the 14-and-2 Dolphins
      • the 13-and-3 Denver Broncos
      • the 12-and-4 Seattle Seahawks
      • the 11-and-5 Los Angeles Raiders
      • the 10-and-6 Chicago Bears
3. the 1985 Chicago Bears, who lost to the Miami Dolphins 24-38 in their thirteenth game
   • the 1985 Bears played a distinctly stronger schedule than the 1984 49ers
   • they crushed three opponents in the playoffs, beating unexpected opponents the New England Patriots 46-10
   • The 2007 Patriots achieved a "perfect regular season" of 16-0 and continued their success against the Jacksonville Jaguars and San Diego Chargers, but lost to the New York Giants 14-17 in Super Bowl XLII.
   • This team was sometimes called the "Cheatriots" because of a "Spygate" incident where they filed plays on the sideline against the New York Jets.
