As the NFL becomes more pass-heavy, the slot receiver role continues to evolve -- and grow in importance.

The slot position naturally gained significance with more teams using three wide-receiver sets. Then, offensive coordinators began lining up their most dangerous weapons in the slot, creating huge mismatches.

From 2005-09, an average of 13.8 players per season saw 50-plus slot targets. That number climbed all the way to 22.2 during the 2015-19 seasons. We've seen top-end receivers such as DeAndre Hopkins, Allen Robinson, Tyreek Hill and Chris Godwin be used more heavily from the slot in recent years, after beginning their careers almost exclusively as perimeter threats.
