Thanks to the nflFastR project and NFL NextGen Stats for the timely sources of data. Commentary will be brief but feel free to let me know in the comments that stats aren’t everything. (click charts for larger view)

For those of you new to this, I will publish key QB stats each week judging how well the Colts passing game performed. I will probably modify the charts throughout the season.

NOTE: references to weekly ranks are of the 30 team QBs through Sunday night


When people describe Wentz, I keep hearing words like “tough”, “strong arm”, “mobile”. You know that is not an alternate way of saying “good”, right?

Less than 1 of 3 Wentz dropbacks were successful and his 32.5% Passing Success Rate was the worst of any week 3 QB. His -0.19 epa per dropback was 27th.

Everything was worse . . . much, much worse.


His yards per attempt never even sniffed the acceptable range.

Through 3 weeks, he is 21st in ypa, driven by the 28th shortest passes. Bad combo.

Air depth on both attempts and (5.4 yds) and completions (4.2 yds) dropped back to the “I can only check-down” range.


Does it even matter?

For the next image, notice the utter absence of blue dots in the upper right quadrant of the chart on the left? That’s where Colts receivers who added greater than average value on longer than average passes would have been . . . you know . . . had there been any.


51.4%. That’s a completion rate not a presidential approval rating. A -13.3% cpoe suggests an average QB . . . average . . . would have completed 64.7% of those attempts. I’m not great at math but that seems below average. No, wait, I am great at math.


And now we come to everyone’s favorite stat to harp on this year.

For those claiming that Wentz’s previous time to throw numbers were upwards biased because he was running for his life, then here is some proof. He clearly could not run for his life this week and his TTT dropped to 2.7 (about league average).

For the 5th shortest attempts, that’s still too slow. He is gun-shy, which combined with very short passes is quite Brissettish.


Short attempts (26th adot) with slightly less than expected yac and league worst accuracy (30th cpoe) combine for the 4th shortest yards per attempt. Add on top of that, a basically average sack rate and no scrambles and you get the 26th ranked net yardage efficiency (ny/d).

There were no turnovers on drop-backs, but there were also no TDs and the 2nd lowest first down conversion rate, so with poor yardage efficiency, that makes the epa efficiency bad (27th).

Here is his year to date dashboard (of 32 QBs). People can argue all they want about how good he may have played in an alternate universe with a better surrounding cast, but the fact is that his numbers have been horrible. They were horrible last year and they aren’t much better so far this year.
