Intended air yards (IAY)
Intended air yards are the total distance a quarterback's passes travelled past the line of scrimmage, whether or not they were caught. Matthew Stafford led 2025 with 5,428 across 597 attempts, and the Rams led all 32 offenses with the same figure.
Every pass carries air yards: the distance from the line of scrimmage to where the ball was aimed. Add them up over a season and you have intended air yards. Nothing about the outcome enters it — a drop, an interception and a 40-yard touchdown on the same throw all count identically — which is why the word is intended.

Why it matters
It separates what an offense tried from what it got. Two quarterbacks can finish within a hundred passing yards of each other and be a thousand apart here, and that gap is the appetite for throwing downfield rather than any measure of accuracy. In 2025 Stafford and the Rams led at 5,428; the Raiders were last at 3,208, a difference of more than two thousand yards of intent across the same seventeen games. Divide by attempts and you get the per-throw version, which is the same idea as a quarterback's average depth of target and is the number to read when volume would otherwise decide the list.
The counter
It is a measure of ambition, not of quality. A quarterback can lead the league in intended air yards by throwing deep and missing, and the total rewards whoever attempted the most passes.
