What Third down pct (allowed) is

Third-down conversion rate allowed: third downs opponents converted divided by third downs they faced against this defense, as a percentage. The share of third downs the defense failed to get off the field on.

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

In 2019 the Patriots led at 24.23; the league average was 39.69.
