What NY/A (allowed) is

Net yards per attempt allowed: opponent passing yards minus the sack yards this defense took back, divided by opponent attempts plus sacks. Yards per attempt allowed with the defense's sacks priced in — a truer read of pass defense than raw yards per attempt.

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

In 2019 the 49ers led at 4.38; the league average was 5.89.
