Question: Which team has more NFC Championship wins, the Green Bay Packers or the Minnesota Vikings? Passage:In his first season in 1997, the 49ers went during the regular season, earning home-field advantage in the playoffs in the National Football Conference (NFC). After defeating the Minnesota Vikings in the divisional round, San Francisco hosted the Green Bay Packers in the NFC Championship Game, but in a muddy, rainy contest at Candlestick Park. The defeat was the 49ers' fourth NFC title loss of the 1990s, following losses to the New York Giants in 1990 and the Dallas Cowboys in 1992 and 1993, and it was their third playoff loss to the Packers in as many seasons. In 1998, the 49ers posted a 124 record and returned to the playoffs as a wild-card team, but to the eventual NFC champion Atlanta Falcons. Two losing seasons followed, but in 2001, the 49ers returned to the playoffs after season, once again to be eliminated by the Packers.
