What Pass int perc (allowed) is

Interception rate forced: interceptions divided by opponent pass attempts, as a percentage. The rate version, so a defense that faces a lot of throws is not flattered by volume.

Higher is better. It is a rate, so a team's number does not grow with games played. Source: P + N.

In 2021 the Patriots led at 4.26; the league average was 2.33.
