Record: 15-3, NFC West champions
The 49ers reeled off 10 straight victories to open the 1990 season, they had the NFL's best won-loss mark for the second straight year (14-2), and they won the NFC West for the fifth straight year.
But the 49ers fell just a matter of seconds short in their quest to "threepeat" in the Super Bowl.
In the NFC Championship Game, the New York Giants battled the 49ers to a 6-6 tie at halftime, and the Niners led 13-9 at the end of the third quarter. Joe Montana was knocked out of the game with a broken hand and a concussion midway through the fourth quarter. With Steve Young at quarterback, a 13-12 lead and 2:36 to go, running back Roger Craig fumbled. Giants linebacker Lawrence Taylor recovered the ball, and the Giants drove for a 42-yard field goal, giving the 49ers a 15-13 defeat on the last play of the game.
Nevertheless, with a two-year record of 32-5, George Seifert was succeeding where others had failed -- he had replaced a "legend." Seifert was named 1990 coach of the year by the Washington Touchdown Club, The Sporting News and The National.
