In the 1979 through 1988 seasons, the 49ers went 102-63, with one tie, a 10-10 game in Atlanta on October 19, 1986. This includes the Niners’ 14 playoff games during the 10-year span. The 49ers scored 4073 points in the 166 games; the opposition scored 3174 points. This works out to an average of 24.5 points per game for the 49ers, 19.1 points per game for the opposition.
In their 102 wins, the 49ers scored 2994 points, or 29.4 per game, and their opposition scored 1526 points, or 15 per game.
In their 63 losses and 1 tie, the 49ers scored 1079 points, or 16.9 per game, and their opposition scored 1648 points, or 25.75 per game.
I could pick through the ’79 through ’88 seasons for trivia for a long time, but I’ll limit it to this: during these years, the 49ers gave up 50+ points in a game once, to Dallas on Oct. 12, 1979. A week earlier, they allowed 48 to the Rams.
They scored 50+ points once, in a 51-7 win over Minnesota on Dec. 8, 1984. They scored 45 to 49 points in a game five times, and allowed 45 to 49 points in a game twice, most infamously in the 49-3 playoff loss to the Giants to end the 1986 season.
