The rate at which NFL teams go for it on 4th & 2-or-less is at an all-time high largely due to the increased use of analytics in decision making.
Note: Percentages shown are how often a team went for it (did not kick a field goal or punt the ball) when it was 4th & 2-or-less and in game-neutral situations (win probability between 20% and 80%). Plays that were nullified due to penalties are not included.
