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

<P0-S0> The Minnesota Vikings season was the franchise's 22nd season in the National Football League. <P0-S1>  This was Minnesota's first season in the newly constructed Hubert H. Humphrey Metrodome. <P0-S2>  The team was looking to improve on its 7-9 record from 1981. <P0-S3>  However, a players strike cancelled 7 of the team's 16 games, and each NFL team was only allowed to play 9 games. <P0-S4>  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. <P0-S5>  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. <P0-S6>  After a loss to the Dolphins, the Vikings would win their next 2 games to sit at 4-3. <P0-S7>  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). <P0-S8>  In the playoffs, the Vikings would defeat the Atlanta Falcons 30-24 to reach the divisional round. <P0-S9>  However, in that game, they would lose 21-7 to the eventual champion Redskins. <SEP> <P1-S0>  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. <P1-S1> 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. <SEP> <P2-S0> Mackensie Alexander (born November 12, 1993) is an American football cornerback for the Minnesota Vikings of the National Football League (NFL). <P2-S1>  Alexander played college football at Clemson University, where after redshirting his freshman season, became a key role player on the Tigers' defense his second season, earning freshman All-American honors. <P2-S2>  Entering his sophomore season, he was a key part of the Tigers's defense, which was ranked among the best in all of college football. <P2-S3>  Alexander was drafted by the Vikings in the second round, 54th overall of the 2016 NFL Draft. <SEP> <P3-S0> The 1982 Miami Dolphins season was the team's seventeenth in the National Football League. <P3-S1>  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. <P3-S2>  The Dolphins had clinched the 2 seed and were picked by many to reach the Super Bowl during the 1981 season. <P3-S3>  After a loss to Tampa Bay, they defeated the Minnesota Vikings 22-14. <P3-S4>  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. <P3-S5>  The Dolphins looked to improve on their 11-4-1 record from 1981. <P3-S6>  Because of this, the NFL schedule was shrunk to 9 games. <P3-S7>  The Dolphins started out fresh, winning their first 2 games prior to the strike. <P3-S8>  When season play resumed 2 months later, the Dolphins defeated the Buffalo Bills 9-7 in Buffalo to clinch a 3-0 start. <P3-S9>  The next week, they lost a brisk game against the Patriots 3-0 in a game called the Snowplow Game. <P3-S10>  The Dolphins would then win 3 straight games to end the season 7-2, tied for 2nd in the AFC with the Cincinnati Bengals. <P3-S11>  In the playoffs, they defeated the Patriots in a rematch by the score of 28-13. <P3-S12>  They then defeated the Chargers in a rematch of the 1981 Divisional Playoffs by a score of 34-13. <P3-S13>  In the AFC Championship game, they shutout the Jets, 14-0 to reach the Super Bowl for the first time since 1973. <P3-S14>  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.
