Question: What key role did the stadium's snowplow operated play in the game following the Dolphins win against the Minnesota Vikings?

The Minnesota Vikings season was the franchise's 22nd season in the National Football League.  This was Minnesota's first season in the newly constructed Hubert H. Humphrey Metrodome.  The team was looking to improve on its 7-9 record from 1981.  However, a players strike cancelled 7 of the team's 16 games, and each NFL team was only allowed to play 9 games.  The Vikings would win their opener against the Tampa Bay Buccaneers before losing the next week to the Buffalo Bills, a game in which they had a 19-0 lead before the Bills pulled off a miraculous comeback to win 23-22.  After the strike ended, the Vikings would get embarrassed in Green Bay against the Packers 26-7 before beating the Bears the next week 35-7 to sit at 2-2.  After a loss to the Dolphins, the Vikings would win their next 2 games to sit at 4-3.  In their final game of the season, they would upset the Dallas Cowboys 31-27 to clinch the NFC's 4th place spot in the playoffs (as divisions were ignored in 1982 and the standings were determined by conference).  In the playoffs, the Vikings would defeat the Atlanta Falcons 30-24 to reach the divisional round.  However, in that game, they would lose 21-7 to the eventual champion Redskins. <SEP> The 1982 Miami Dolphins season was the team's seventeenth in the National Football League.  The team was coming off an unexpected 11-4-1 1981 season and a devastating loss to the San Diego Chargers in the Divisional Round the previous season in a game dubbed the Epic in Miami.  The Dolphins had clinched the 2 seed and were picked by many to reach the Super Bowl during the 1981 season.  Because of the high number of picks to reach the Super Bowl the previous season, many more fans picked them to win it during the 1982 season.  The Dolphins looked to improve on their 11-4-1 record from 1981.  However, a players strike cancelled 7 of the team's 16 games.  Because of this, the NFL schedule was shrunk to 9 games.  The Dolphins started out fresh, winning their first 2 games prior to the strike.  When season play resumed 2 months later, the Dolphins defeated the Buffalo Bills 9-7 in Buffalo to clinch a 3-0 start.  The next week, they lost a brisk game against the Patriots 3-0 in a game called the Snowplow Game.  The Dolphins would then win 3 straight games to end the season 7-2, tied for 2nd in the AFC with the Cincinnati Bengals.  The Dolphins won 2nd place over them by virtue of a series of tiebreakers.  After a loss to Tampa Bay, they defeated the Minnesota Vikings 22-14.  In the playoffs, they defeated the Patriots in a rematch by the score of 28-13.  They then defeated the Chargers in a rematch of the 1981 Divisional Playoffs by a score of 34-13.  In the AFC Championship game, they shutout the Jets, 14-0 to reach the Super Bowl for the first time since 1973.  In Super Bowl XVII, they lost to the Redskins 27-17 in a rematch of Super Bowl VII which concluded Miami's perfect 1972 season. <SEP> Mackensie Alexander (born November 12, 1993) is an American football cornerback for the Minnesota Vikings of the National Football League (NFL).
