Opposing QB Stat Tracker: Week 14

NFL: New England Patriots at Buffalo Bills Mark Konezny-USA TODAY Sports

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 top 32 QBs by attempts through current week.


Here is what Mac Jones has looked like on the season.

He has faced higher than average passing defenses (10th opd) on a run-first team (27th ed%) that has been very successful on the ground (8th arsr). He gets rid of the ball very quickly (29th ttt), which helps manage opponent pressure (26th pr%), but that is at the cost of below average passing length (21st aDOT).

His receivers primarily catch the shorter passes (22nd ay/c) and accumulate average yac (16th yac, 14th yacoe), but they don’t have much success downfield (21st 20+e). However, Jones’ accuracy is very good (4th cpoe), which turns those short passes into decent yards per attempt (12th 7.5).

His sack rate is high relative to the amount of pressure he sees (18th sk%, 26th pr%), but it is still below league average. He doesn’t scramble much (25th scr%), opting to throw the ball away instead (18th ta%) . However, his overall reactions to pressure dilutes his yards per attempt and so his net yardage efficiency is just average (17th ny/d).

His turnover rate is below average (20th to%), but so his is TD rate (19th td%). He makes up for that a bit, by being OK at getting first downs (15th 1st%). Combined with his average yardage, that results in an overall efficiency and success rate that is slightly better than the average QB (14th psr, 15th epa/d).


He has similar efficiency to Carson Wentz, but his success rate is higher. This implies that Jones does not rely as much as Wentz on explosive plays for efficiency.

I hesitate to include week 13 in these next charts as Jones had only 3 passing attempts all game. I wonder if NE fans were yelling at Belichick to throw the damn ball?

Overall, Jones has been trending better throughout the year but has been highly volatile resulting in overall average numbers. Why does that sound familiar?


His passing depth has been declining since early in the season.


He spread out his passes well in week 13 . . . all 3 of them. When Jones is actually passing the ball, Jakobi Meyers receives the most targets by far, but Kendrick Bourne gets almost the same yards.

Jones’ range on TD passes isn’t anything unusual.


This is where he shines. Even accounting for the shorter pass distance, his accuracy has been very good.


Much like a previous Belichick QB, Jones wastes no time in getting rid of the ball.


This reinforces the lack of success downfield. He is about average in mid-range throws and the team executes screens well.
