The 1991Indianapolis Coltsseason was the 39th season for the team in the National Football League and eighth in Indianapolis. The team was looking to improve on the 7–9 record they had recorded in 1990, but not only failed to do so but regressed so far that the team was forced to fire head coach Ron Meyer during the season. The Colts were victorious only once in the regular season, finishing last in the AFC East, and their fifteen losses tied an NFL record set by the 1980 New Orleans Saints. The Colts were the third team in as many seasons to finish with a single victory, as the 1989 Dallas Cowboys and 1990 New England Patriots each duplicated that mark. However, the 1991 Colts had a much weaker schedule to play than either the 1990 Patriots or 1989 Cowboys, playing eleven games against teams with non-winning records, as against only five for the 1990 Patriots and four for the 1989 Cowboys. Their only victory came against their division rivals, the New York Jets, in Week 11 at Giants Stadium (the Colts went 0–8 at home in the Hoosier Dome).
The Colts scored the fewest points up to that point (143) of any team in NFL history in a sixteen-game schedule. Statistics site Football Outsiders said of the Colts 1991 season: "It's the flipside of [Super Bowl champion] Washington; the Colts were the worst offense and defense in the league in the second half of close games, and the worst offense in the league in the first quarter.
Football Outsiders continues, "The worst quarterback in the league, based on total value, was [Colts quarterback] Jeff George, who was in his second year with the Colts [....] despite having an above-average completion rate: over 60 percent when the NFL average was 57.4 percent. The issue here wasn't really turnovers, as George threw only 12 picks. However, George was Captain Checkdown with a league-low 8.3 yards per completion, and he took a league-leading 56 sacks. He did this against one of the easiest defensive schedules in the league."
^The league switched from a 14- to a 16-game schedule in 1978. The team never scored more than 28 points in any game (doing so in their lone victory), scored less than ten points eleven times, were shut out twice, and failed to score at least one touchdown in nine of their sixteen games.
^The 1991 Colts’ total is now second-lowest of all-time, behind the 140 points the Seattle Seahawks put up in 1992.
