The Vikings-Bears rivalry dates to the first game in Vikings history in September 1961, which Minnesota won 37-13 at Metropolitan Stadium. On Monday night they will play their 111th game against each other, with the Vikings holding a 57-51-2 series edge.
But in 1961, no expansion franchise had ever won the first game of their inaugural season. The Vikings were led by coach Norm Van Brocklin, and faced the great George Halas, who did everything imaginable for the Bears.
And while the Vikings won that first contest, they finished 3-11 that year.
Quarterback Fran Tarkenton, who was a rookie and didn't start against the Bears, remembers every detail of the game. He recently recalled what he said was the greatest upset in Vikings history, and maybe one of the greatest upsets in NFL history.
"It was 1961. We were a new expansion team. No new expansion team had ever won [an opening] game in their first season," Tarkenton said. "The Dallas Cowboys came in the year before we did in 1960. Tom Landry, Hall of Fame coach, Don Meredith, a great quarterback, and they played 12 games and didn't win a game [going 0-11-1; the NFL initiated a 14-game schedule in 1961].
"Here we're playing the opening game against the Chicago Bears. We'd lost five exhibition games already, the Bears had beaten us, drummed us like [30-7] two weeks before in an exhibition game in, of all places, Cedar Rapids, Iowa. Now we would play the Bears [again]. We were 28-point underdogs."
Tarkenton explained why the Vikings were such big underdogs and why expansion teams had a hard time winning games.
"Now I'm going to tell you how we got our players," he said. "Every team in the league had 40-player squads. They got to [keep] their 34 top players; nobody has 34 top players. … We got to pick three of the bottom six [from each of the other 13 teams] and then a regular [college] draft. That's why these teams couldn't win their first year, that's what we had to play with.
