Quarterback Joe Montana had one of the greatest statistical passing seasons in NFL history in terms of efficiency in 1989.
Montana set a then-NFL record with a passer rating of 112.4,[4] with a completion percentage of 70.2%, and a 26/8 touchdown-to-interception ratio.
Quarterback Joe Montana threw for 3,512 yards, 26 touchdowns, and only 8 interceptions, giving him what was then the highest passer rating in NFL history (112.4).
Wide receiver Jerry Rice had another outstanding season, catching 82 passes for 1,483 yards and 17 touchdowns.
With all of these weapons, San Francisco's offense led the league in total yards from scrimmage (6,268) and scoring (442 points).
Three starters from the defense made the 1989 All-Pro Team: Ronnie Lott, Don Griffin, and Michael Walter.
The Niners fell behind 21–10 in the fourth but despite giving up a safety Joe Montana erupted, outscoring the Eagles 28–7 and throwing for 428 yards and five touchdowns in total, winning 38–28.
This game was played at Stanford Stadium, as Candlestick Park had sustained damage in the Loma Prieta earthquake five days earlier.
The Niners fell to the Green Bay Packers in what would be their final loss of the season, as Don Majkowski ran in two touchdowns and threw for a third, overcoming 325 yards by Joe Montana, who was sacked five times.
In what many 49ers fans consider one of the greatest regular-season wins in team history, the 49ers came back from a 27–10 4th-quarter deficit to beat the Rams 30–27.
The Rams had already beaten the 49ers earlier in the year and looked poised to do it again, but the 49ers, with help from John Taylor's big game, took the lead late with Roger Craig's 1-yard touchdown.
