Opponent QB Stat Tracker: Week 2

NFL: Tennessee Titans at Seattle Seahawks Joe Nicholson-USA TODAY Sports

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)


HOW WELL?

Ryan Tannehill had a horrible opening week against the Cardinals, but he put it to the Seahawks in week 2.


HOW FAR?

He has the 5th longest depth of completed passes on the 10th longest attempts, but due to 1 INT and 3 sack fumbles, his cumulative epa is low.

His TD passing depth is a bit longer than average.


TO WHO?

Julio Jones is still a thing.

A.J. Brown is a deep threat for them.


HOW ACCURATE?

Overall accuracy is below average, but not terrible.


HOW FAST?

Stafford has the 15th longest time to throw, but the 4th highest sack rate with 9 sacks.


DASHBOARD

His week 1 and week 2 were so different, that I’m not sure that combined data tells you a lot about what to expect, but here goes anyway.

Long throws combined with lower than expected yac equals basically average yards per attempt (19th). Lots of sacks drag the net yardage down (21st). He has decent first down conversions (15th), but a high turnover rate (5th) and a low TD rate (27th) are anchors on his efficiency (28th epa/d), even though the bulk of his passing plays adds positive value (13th psr).

Basically, when he doesn’t turn the ball over, he is dangerous, but his 2 weeks so far are not as good as his play over the last few seasons.
