Thanks to the nflFastR project and NFL NextGen Stats for the timely sources of data.
For those of you new to this, I will publish key QB stats each week judging how well the Colts passing game performed. Yes, O-Line, receivers, and play-calling impact these numbers but they are primarily QB measures. I will probably modify the charts throughout the season. Commentary will be brief but feel free to let me know in the comments that stats aren’t everything. (click charts for larger view)
NOTE: All references to rankings are of the 28 QBs that have played as of Sunday night.
50 drop-backs is a bit more than the 21 that Carson Wentz had last week. The sack-fumble and the first interception completely wrecked his epa efficiency for the day, landing him at a slightly below league average +0.06 epa/d.
Outside of those 2 disastrous plays though, he passed the ball pretty well. Unfortunately, those plays count, and they also dropped his success rate below 50%.
Not only was his epa/d and psr about league average, so was his 1st down conversion rate and net yards per drop-back.
All of those numbers are basically average for the week, the trailing 5 weeks, and the season. So, I feel I am on firm ground when I say, he has been playing like an average QB.
There was a good mix of passing depth with lots of attempts over 20 yards. Yards per attempt was below league average but matched his season total (7.0 ypa).
He stretched the field a lot. Overall, his passing depth was farther than usual (7th longest this week) and his 7.9 yard avg completion depth was 4th longest.
HIs season 7.0 yards per attempt comes in at 21st (of 32), with the air yard portion of that ranking 24th.
For the 2nd week in a row, the leader in receiving yards was Jack Doyle. I really hope I don’t have to say that every week.
Looking at the season graph, it’s clear that our receiving threats are Pittman and then “other”.
This week, only Doyle wins the elusive “better than average value on longer than average passes” award.
A 61.4% completion rate is about 6% below expected, so accuracy (drops) wasn’t that great.
For the second week in a row, Wentz got rid of the ball quickly and he did so with long pass attempts. That is a promising turn of events.
Despite a 62 yard TD pass that traveled 52 air yards, Wentz's deep passing was not very efficient.
On the year, it is a different story. By epa efficiency, he is the 6th best QB on passes >= 20 yards.
Here is the comparison to the 27 other QBs that have played so far this week.
The Colts went pass-heavy (8th ed%), even though they were efficient on the ground (5th arsr).
Wentz threw quick passes (23rd ttt), but still managed long attempts (7th adot, 10th 20+) with unfortunately below-average accuracy (18th cpoe). The receivers did not add much yardage after the catch (26th yac, 22nd yacoe), so that all blends together for average yardage efficiency (7.0 ypa 12th).
Wentz had some sack trouble this week (10th sk%) and so that 7.0 ypa drops to 6.1 net yardage efficiency (17th ny/d).
He had 3 turnovers (5th to%) but also had 3 TDs (7th TD%). His 34% first down conversion rate (13th 1st%) showed that he was moving the ball well.
Overall, his game epa efficiency ranked 15th (+0.06 epa/d), which is similar to his season ranking (16th +0.12).
