There are some New York baseball fans still upset with the Stoneham family for moving their Giants team west to San Francisco after the 1957 season. But that only has only added to the passion of the New York football Giants fans over the years when they've met with their brethren in San Francisco during the NFC playoffs several times in the past three decades.
The New York Giants and San Francisco 49ers first met in the post-season at the end of the 1981 NFL season. San Francisco, behind quarterback Joe Montana, prevailed and went on to win the franchise's first Super Bowl over the Cincinnati Bengals.
The two teams met three more times in playoff games during the 1980s, playing in consecutive seasons from 1984 to 1986. In that last year, the Giants won their first Super Bowl over the Denver Broncos.
Then, at the end of the 1990 season, the Giants and 49ers faced off for the first time in the NFC championship game in San Francisco. In a tough defensive struggle, the Giants prevailed behind five Matt Bahr field goals, 15-13.
The Giants and 49ers met twice more in the playoffs in subsequent years. San Francisco beat New York in a 1993 NFC divisional playoff game and a 2002 wild card contest.
What to expect this Sunday
The 1990 NFC championship game could offer a window on this Sunday's contest, as the Giants once again boast a highly-rated defense. And the 49ers, despite giving up 32 points to the New Orleans Saints in the divisional playoffs last Saturday, have a defense that has improved steadily throughout this 2011 season.
Is it ever in a NFL playoff match?
Both teams field productive offenses, with the biggest difference coming at quarterback. Eli Manning of the Giants is a seasoned leader, and has a Super Bowl MVP award to his credit. The 49ers' Alex Smith will be enjoying his first NFL playoff go-around.
