I was messing around with some adjusted passer ratings a few weeks ago and a lot of the responses wanted Rushing contributions to be included. So I came up with a new method to do so, combining the adjusted Passer Rating (Passer Rating without Drops, Spikes, Throwaways) with Rushing production. That produced what I call QB CPR.
^(Full disclosure: I am a 49ers fan, but I did not do this to overhype Purdy. He was not atop this list when I started (Cousins, Goff, & Stroud were 1, 2, & 3, respectively. Ignore my flair and you will still see differences like Goff, Wilson, and Mahomes vs their traditional rankings.))

GUIDE:
- CPR = Adjusted Passer Rating + Rushing Production
- Adjusted Passer Rating = Passer Rating after eliminating Drops, Throwaways, & Spikes
- Combined with Rushing Yds, TDs, & Fumbles Lost
- C-Yd = Combined Yards (Rushing + Passing)
- C-TD = Combined TDs (Rushing + Passing)
- C-TO = Combined Turnovers (Rushing + Passing)
- C-YPA = Combined Yards Per Attempt (Rushing + Passing)
- C-TD% = Combined TD% Per Attempt (Rushing + Passing)
- C-TO% = Combined Turnover% Per Attempt (Rushing + Passing)
CPR2
While doing all this I was looking for another metric to account for players that were doing the majority of the work. That is to say, not benefiting strictly of YAC. So I came up with another metric for this. CPR2 takes the original CPR metric and strips the YAC.
- As an example, it is much harder to earn a perfect rating this way.
- Keenan Allen is 1/1 for a 49 yd TD. Under both standard and my CPR Rating that would be a 158.3 Rating. However, with CPR2 that becomes a 142.2 Rating. In this rating, perfect means perfect. K.Allen would have had to throw 1/1 for 49 Air Yards on a TD.

Guide:
- CPR2 = Takes CPR and adjusts it toward the % of a player's total yards are not from YAC.
- This is designed to give a more accurate picture of what a QB is doing (as both a runner & passer) separate from the receiver.
- AYPC = Air Yards Per Completion
- YAC/Cmp = Yards After Catch, per Completion
- CRAY = % of Combined Yards from Rushing and Air Yards
- CYAC = % of Combined Yards from Yards after the Catch
Stats vs Context
- A stat like Passer Rating is just a stat. It doesn't give context. You still have to take the stat and apply context to it.
- CPR is just a stat. You still have to apply context to it. But hopefully, this gives a more accurate piece of the picture than basic passer rating.
Common Q&A:
- Does CPR2 favor QBs who have a very strong arm and launch a lot of deep balls?.
- No. Arm Strength is a routine criticism of Purdy. But he can functionally throw an accurate deep ball without the greatest arm strength.
- Does CPR2 favor QBs who launch a lot of deep balls?
- Not necessarily. R.Tannehill leads the NFL in Intended Air Yards per attempt. Watson is 2nd, J.Love is 4th. But none of them rank that highly overall.
- Does CPR2 hurt QBs who get a lot of YAC?
- No. When you look at Stroud you can see he leads the NFL in Air Yards per completion. But he is also 6th in YAC/Cmp. Purdy is 2nd & 1st. Tua is 6th and 3rd. It is possible to get both Air Yards and YAC.
- Why punish checkdowns?
- the design is not to "punish" anyone. CPR2, specifically, is designed to credit those that are doing more outside of YAC, specifically including on the ground, which is the original criticism I was addressing.
- Why strip away YAC:?
- Stripping YAC shows more of the individual contribution, especially with the legs. Which is why you see good runners like Hurts and Lamar take a leap. Their traditional passer rating, invented before the age of mobile QBs, doesn't properly give them credit for this overall play.
If you adjust their completion rate on first and second down and make them incomplete passes instead, then most of these QBs have really bad stats
