Yes, there have been a few NFL games in history where both teams scored a combined total of 100 points or more. In fact, there have been a total of six NFL games in history where the two teams combined for 100 or more points.
The first NFL game to ever reach the 100-point mark was played on November 27, 1966, between the Washington Redskins and the New York Giants. The game, which was played at the old Yankee Stadium in New York, saw the Redskins win 72-41. The total score of the game was 113 points, which is the highest combined score in an NFL game to date.
The second-highest-scoring NFL game of all time took place on November 10, 1985, between the Cincinnati Bengals and the Cleveland Browns. The Browns won the game 51-45, with the two teams combining for a total of 96 points.
The third-highest-scoring game in NFL history took place on November 15, 1992, between the Seattle Seahawks and the Kansas City Chiefs. The Seahawks won the game 38-31, with the two teams combining for a total of 97 points.
The fourth-highest-scoring game in NFL history took place on October 23, 2011, between the Buffalo Bills and the Oakland Raiders. The Bills won the game 38-35, with the two teams combining for a total of 97 points.
The fifth-highest-scoring game in NFL history took place on November 19, 2017, between the Los Angeles Rams and the Kansas City Chiefs. The Rams won the game 54-51, with the two teams combining for a total of 105 points.
Finally, the sixth-highest scoring game in NFL history took place on December 13, 2020, between the Baltimore Ravens and the Cleveland Browns. The Ravens won the game 47-42, with the two teams combining for a total of 89 points.
It is worth noting that these high-scoring games are relatively rare in the NFL. Most games tend to have a much lower score, with the average score in the NFL typically falling between 40-50 points. However, when two high-powered offenses face off against each other, it is always possible that the game will turn into a shootout with a high combined score.
