In the 2021 season, per Sports Info Solutions, NFL teams targeted their slot receivers on 39.7% of all passing attempts (7,496 of 18,881). 43.1% of all catches (5,481 of 12,731) came from the slot, as well as 35.6% of all receiving yards (49.737 of 139,619), 51.7% of all yards after the catch (35,567 of 68,802), 49.7% of all yards after contact (12,025 of 24,176), and 36% of all passing touchdowns (320 of 889).
The point? Slot receivers are more important than they’ve ever been before. As the NFL moves to more and more 3×1 formations, offenses don’t just rely on one slot receiver — there are now multiple slot weapons per team, serving different roles. Whether those slot targets are smaller receivers, bigger receivers, running backs, or tight ends, if you’re not attacking opposing defenses (which are trending far more to nickel and dime sets to counter all this), you’re not doing the most you can do as a play-designer.
If the first thing you thought after reading this was, “I bet the Seahawks don’t do enough to attack opposing defenses in the slot,” you would be correct. Seattle had the NFL’s fewest slot targets by far in the 2021 season, with 164. The Vikings, 49ers, Bills, and Saints rounded out the bottom five.
