What Is a Quarterback Rating?
A Quarterback Rating (Passer Rating) is a statistical measure used to evaluate the performance of a quarterback in football. It combines multiple passing statistics into one single number.
A higher rating means better performance, while a lower rating indicates poor passing efficiency.

This makes it easier to compare quarterbacks fairly across games and seasons.
