Just a rating that tells you how good a quarterback is.

Answer 3

A rating is a (complicated) formula that shows how goo a QB is. The highest in the NFL is 158.3, while the low is 0. A good rating would be about 85, great is 95, and awesome is above 100. Below 80 is bad. Joe Montana has the highest career QB rating of all time.
