The Vikings and Dolphins play on Sunday for only the 12th time, and the first two meetings were remarkably important in the histories of the two storied franchises.
In 1972, the Dolphins went 17-0 to complete the only perfect season in NFL history. But had it not been for a late roughing the passer penalty against the Vikings in Week 3 at old Met Stadium, there would have been no run of perfection.
The Vikings led 14-6 with under five minutes to play when Garo Yepremian kicked a 51-yard field goal to cut the deficit to 14-9. Up to that point in his career, that was the longest field goal Yepremian had ever made.
The Vikings were being quarterbacked by Fran Tarkenton, who had returned to the Vikings in '72 after spending five years with the New York Giants, and the offense went three-and-out and gave the ball back to Miami.
Then the Dolphins got their biggest break of the season when Vikings defensive lineman Bob Lurtsema was called for roughing the passer on second-and-8, which gave Miami a first down at the Vikings 42-yard line with 1 minute, 20 seconds to play. Four plays later, the great Bob Griese connected on a 3-yard touchdown pass to tight end Jim Mandich and the Dolphins won 16-14.
If that penalty hadn't been called, there is no doubt the Vikings would have won the game and the Dolphins' unbeaten season would have never happened.
The Vikings' Purple People Eaters had done a tremendous job shutting down the great running back tandem of Larry Csonka (66 rushing yards) and Mercury Morris (28) in that game, but the roughing the passer call completely swung the momentum to the Dolphins.
How big was the play? Various rumors exist that then-Dolphins coach Don Shula or linebacker Nick Buoniconti sends Lurtsema a Christmas card every year.
