Given the proliferation of committee backfields, each NFL defense will face usually two or three running backs in the course of most games. Turning in one of the best eight games allowed by a secondary is an elite performance considering that defense.
Below shows how often a player logged the best game allowed by a secondary (Top-1), one of the four best performances allowed (Top-4), and one of the best eight performances (Top-8). With 17 games played, a Top-8 game is “above average” among the best running back from each opponent.
The “Better than Average” (BTA) score is a weighting of those games.
