I was so stoked to watch the Pittsburgh Steelers defeat the Indianapolis Colts (in one of the most shocking upsets in years) that I decided to take care of an annoyance that the various sites that cover football have caused me.
The NFL uses a rating system that is a rather gross approximation of a quarterback’s perfomance. You’ll hear about this rating all the time, but not how it is calculated. I looked on the Internet, and found only one site that had an online calculator for the rating. Except that it was broken, and didn’t work.
So I looked up the formula, and implemented it myself. Football fans who are interested can find the QB Rating calculator here. The worst score is 0.0, and the “perfect” score is 158.3. A good score is probably above 85 or so in today’s league.
