What NY/A (Off − Def) is

Net yards per pass attempt minus net yards per attempt allowed — passing efficiency with sacks priced in, on both sides of the ball. One of the strongest single team measures on this site; teams that win this usually win games.

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