Passer Rating is Outdated, and Needs A Makeover by LBVikings

Passer Rating has largely become the industry standard in the NFL. It’s used in mainstream sports media, broadcasts and forum discussions alike. It gives fans and analysts a nice, clean number on which to judge a passer, rooted in quantifiable fact and not opinion. Aside from the subjectivity from stat-markers (e.g. whether to mark a gain for 8 yards or 9 yards, ambiguous fumble vs. interception cases, etc), there’s not much room to argue passer rating. Nobody says “in my opinion, Sam Bradford had a 95.6 instead of a 99.7″. That’s what makes it a useful tool. I personally cite passer rating all the time, and think it’s largely a reliable stat, albeit imperfect.
But many fans don’t know what passer rating actually is. They couldn’t tell you the formula, or what pieces it uses and in what way. They certainly couldn’t tell you where it came from. So let’s start this piece with a little rundown of passer rating, what it is, and why it works the way it does.
Up until 1971, the NFL had a tough time trying to determine a yearly passing leader. Was it the guy with the most yards? Best completion percentage? Touchdowns? Wins? It’s easier in a sport like baseball where everything that happens contributes to a run, and every run is one point. Football has 2 and 3 and 6 point increments, plus turnovers, and overall a much more complex system on which you have to measure progress. Then-commissioner Pete Rozelle commissioned statisticians, specifically a guy named Don Smith, to fix this problem. You can read the linked anecdote for more of the history behind passer rating, but at the end of it all, we get this:
That looks horrifying, but don’t fret- we’ll break it down. The first thing to do is note that it uses five raw numbers- completions, yards, touchdowns, interceptions and attempts. Not pictured are sacks, fumbles, rushing yards, throwaways or other classifications of QB-related play. We’ll get to that later.
