1989 San Francisco 49ers season

The 1989 season was the San Francisco 49ers' 40th in the National Football League (NFL), their 44th overall and their 1st season under head coach George Seifert. After going 14–2 in the regular season, the 49ers completed the season with one of the most dominant playoff runs of all time, outscoring opponents 126–26, earning their fourth Super Bowl victory and their second consecutive, where they bent over the Broncos, 55–10. They finished with the best record in the NFL for the first time since 1987. Their two losses were by a combined 5 points. In 2007, ESPN.com's Page 2 ranked the 1989 49ers as the greatest team in Super Bowl history. This was the season where the 49ers added the black trim on the SF logo on the helmets which lasted until the 1995 season. Quarterback Joe Montana had one of the greatest statistical passing seasons in NFL history in 1989. Montana set a then-NFL record with a passer rating of 112.4, with a completion percentage of 70.2%, and a 26/8 touchdown-to-interception ratio. In the playoffs, Montana was even more dominant, with a 78.3% completion percentage, 800 yards, 11 touchdowns, no interceptions, and a 146.4 rating. Cold Hard Football Facts calls Montana's 1989 season "the one by which we must measure all other passing seasons."
