On January 26, Beijing time, the NFL officially announced the two referees who will enforce the finals of the American League and the League of Nations. There is a very interesting point, the referee team of the law enforcement League finals likes to throw yellow flags in the regular season, while the referee team of the law enforcement American League finals dislikes throwing yellow flags the most in the regular season.

League referee: Carl Schaefers
Shervers is one of the league's most experienced referees, and the 61-year-old veteran referee has been blowing penalties in the league since he was hired as a sideline referee in 2000. After 8 years as an assistant referee, he was promoted to referee in 2008. During his law enforcement career, Shearers blew a total of 15 playoff games, including two Super Bowl games.
It is worth noting that according to statistics, Schaefers' referee team threw 229 yellow flags this year, the most in the league. He averaged 14.31 fouls per game, the only referee to average more than 14 fouls per game. Let's take a look at the record of both teams over the past five years when Shears has played the Los Angeles Rams and San Francisco 49ers.
Rams: 2 wins and 1 loss (1 win and 0 losses in the 2021 season)
49ers: 4 wins and 3 losses (2 wins and 1 loss in the 2021 season)
In October 2020, Schaefers once blew a Rams-to-49ers game that resulted in the 49ers beating the Rams 24-16.
American League Finals Referee: Bill Winovic
Winovic is considered one of the best referees in the league, which is why he almost always gets called in in big games. The Tigers' game against the Chiefs will be the 16th playoff game of Winovic's law enforcement career, and he has played two Super Bowl games as a referee, as well as six Confederations Cup finals.
Unlike Schaeffers, Winovic's team has thrown almost few yellow flags this year, averaging just 9.25 fouls per game. That's a full 5 fewer fouls than Schaefers' referee team and the least yellow flag thrown in the league. The record of the two teams over the past five years when Vinović law enforcement tigers and chiefs played.
Tigers: 1 win, 5 losses (1 win, 2 losses in 2021)
Chiefs: 6 wins, 3 losses (2 wins and 0 losses in the 2021 season)
Winovic played a Tigers game against the Chiefs in October 2018, when Kansas City beat Cincinnati 45-10. In addition, Vinović has also played several important games for the Chiefs in the past few seasons, such as last year's American League final when the Chiefs beat Bill and the Super Bowl Chiefs defeated the 49ers the previous year.
In addition to this, the league also announced that Ronald Tobert will serve as super bowl referee. Tobert joined the league in 2010 as deputy referee and was promoted to chief referee in 2014. He then blew off six playoff games, including two wild card games and four division games. The most recent law enforcement was a match in which 49 people beat the Packers 13-10 last week. Tobert averaged 12.3 fouls per game in the regular season, ranking fourth in the 17 groups of referees. In the Super Bowl, they will work with another group of referees to ensure that all referees meet the NFL's evaluation criteria.
