All good little posts begin with a stout disclaimer.
DISCLAIMER: Passer rating is flawed. It is descriptive rather than predictive. It can make good quarterbacks look great, competent quarterbacks look incompetent, and it’s too rough of a metric. Doesn’t even take sacks or mobility into account. And what about drops?
That being said, if you want a shortcut stat that’s accessible, you could do a lot worse. Yards/attempt is probably better, but passer rating is a good-enough 35,000-foot metric. That’s why a little investigation into Russell Wilson’s rating, and how it correlates to the success of the Seattle Seahawks, is always on-topic here at the Gulls of Field.
