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

Context:
1995 Minnesota Vikings season
The Minnesota Vikings season was the 35th year of season play for the Minnesota Vikings and the 76th regular season of the National Football League.
 The Vikings finished with a record of eight wins and eight losses.
 The Vikings however had a chance to still make the playoffs entering Week 17 at Cincinnati.
 But with the Bears and the Falcons winning their games to fight for the final spot in the playoffs, it was too much to overcome for Minnesota to clinch.
 This was the first time the Vikings had not reached the playoffs under Green.
Snowplow Game
In National Football League lore, the Snowplow Game was a regular-season game played between the Miami Dolphins and New England Patriots on December 12, 1982, at Schaefer Stadium in Foxborough, Massachusetts.
 The stadium's snowplow operator, Mark Henderson, cleared a spot on the snowy field specifically for New England kicker John Smith so he could kick the game-winning field goal to give the Patriots a 3–0 win.
Minnesota Vikings Cheerleaders
The Minnesota Vikings Cheerleaders are the official cheer squad for the Minnesota Vikings.
 The squad performs at every home game at the U.S. Bank Stadium, the home stadium of Minnesota.

 In 1984, the MVC were started.
 The group currently has 35 members.
 The squad, like other groups in the league, releases a swimsuit calendar annually since 2001.

 Like other NFL cheerleading squads, the MVC also has a "Junior Minnesota Vikings Cheerleaders" program, which has various divisions: Junior Angel Division is for girls aged 3–5, and Junior Cheerleader Division is for girls aged 6–14.
 In April, the MVC hosts tryouts at Winter Park.

 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 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.
 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.
