Accuracy is obviously an important element for an effective offense in today’s NFL. Adjusted completion percentage attempts to measure that, and I wanted to look at that stat courtesy of Pro Football Focus (PFF).
PFF describes adjusted completion percentage as accounting for elements that hurt the passer’s completion percentage, but don’t show how accurate they are. These factors are dropped passes, throw aways, spiked balls, batted passes, and passes where the QB was hit while they threw the ball.
Here’s the formula: ((Completions + Drops) / (Attempts – Throw Aways – Spikes – Batted Passes – Hit As Thrown)).
