Opposing QB Stat Tracker: Week 11

NFL: New York Giants at Tampa Bay Buccaneers Kim Klement-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.


HOW WELL?

Tom Brady is still putting up good numbers at age 44.

His cumulative season rankings for the above numbers are:

  • 6th in epa/d
  • 3rd in psr
  • 4th in 1st%
  • 5th in ny/d


HOW FAR?

In the first 5 weeks, Brady was throwing long passes, as one does in a Bruce Arian’s offense. However, since then, his passing depth has dropped back to just NFL average. The depth of his completions is actually below average.

Yards per attempt is 11th on the season and the air yards portion of that is about average.


TO WHO?

Chris Godwin has the most targets and yards, but Mike Evans has the most air yards, showing he is the deeper threat.

The next chart on the right has the top 2 receivers in the upper right quadrant which is exactly what a potent passing game should look like.

Brady’s TDs come from the same distance as most of the top TD volume QBs.


HOW ACCURATE?

Overall, his accuracy has been good (shocker) ranking 11th in cpoe on the year.


HOW FAST?

As always, Brady gets rid of the ball very quickly, yet he has thrown farther than average. That is exactly what you want your QB to do.


TO WHERE?

On passes longer than 10 yards, he is actually a bit worse than the average QB, but he more than makes up for it between 0 and 10 yards.


DASHBOARD

Against strong passing defenses (7th opd), Tampa Bay has one of the most pass heavy offenses (4th ed%) with a highly efficient rush game (6th wrsr).

Brady releases quickly (31st ttt), helping to avoid pressure (32nd pr%) while still throwing farther than average (11th adot, 9th 20+), but limited success on longer passes results in shorter than average completions (19th ay/c). His higher than average accuracy (11th cpoe) helps support a better than average yardage efficiency (11th ypa) and since he never scrambles or gets sacked (30th scr%, 32nd sk%) that translates to a 5th best net yardage efficiency (7.0 ny/d).

He turns the ball over less than the average QB, but not dramatically so (21st td%). He has the highest TD rate in the league (6.5% td%) and gets a lot of first downs (4th 1st%) showing his solid ability to move the ball down the field. This culminates in the 6th best epa per drop-back (0.22 epa/d).
