The NFL has modified regulations governing what can be displayed on video boards during field goal and extra point attempts, according to multiple outlets. The change comes after the Patriots' longstanding practice of using their video board to create an optical illusion for opposing kickers was exposed.
Per Yahoo Sports, the Patriots displayed goalposts on their video board, creating visual distortion for kickers attempting field goals. ESPN reported that the rule change came in the wake of a viral social media post from a former NFL analytics coach who uncovered the tactic. The specifics of what the new rules prohibit were not detailed in the available reporting.
