Overview

• Researchers analyzed more than 13,000 penalty calls from 2015 to 2023, zeroing in on the postseason as the NFL’s most commercially valuable period.
• Penalties against Chiefs opponents were more likely to produce first downs, greater yardage, and subjective flags such as defensive pass interference or roughing the passer.
• Postseason data since 2018 show a net +272 penalty yards for Kansas City, including +220 across three Super Bowl runs, according to compiled figures.
• The study says a similar officiating pattern was not present for other dynasties, specifically the Brady–Belichick Patriots.
• NFL commissioner Roger Goodell has dismissed the notion of manipulated officiating as a ridiculous theory, even as the findings fuel renewed debate among fans and players.
