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?
On the year, Ryan Tannehill has above average efficiency and success rate.

He has been trending better as the year progresses.

HOW FAR?
His 7.6 yards per attempt ranks 12th among all QBs.

Tannehill’s depth of targets and completions have bounced around but are basically average (17th aDOT, 17th ay/c).

He doesn’t have a lot of passing TD’s (21st TD%) and when they do happen they are from fairly close.

TO WHO?
A.J. Brown and Julio Jones are his passing threats and Julio is out for week 8.

HOW ACCURATE?
His accuracy (cpoe) has bounced around, but on the year he is right about average (17th -0.7%). Past 10 yards, though, he’s not hitting receivers well.

HOW FAST?
I had to double-check his week 7 time to throw. 2.17 seconds is a ridiculously quick average, especially partnered with a 13th ranked aDOT. However, he has had a quick release all year, ranking 23rd.

TO WHERE?
As I previously said, beyond 10 yards Tannehill has not been impressive.

DASHBOARD
Season numbers
:format(webp):no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/22968647/QB_Ryan_Tannehill_Dashboard.png)
Tannehill has faced below average defenses (22nd opd) on a successful run first team (29th ed%, 9th wrsr).
He gets rid of the ball quickly (23rd TTT), but still manages average depth on his passes (17th aDOT, 17th ay/c). He is not a deep threat (25th 20+, 26th 20+e), but his receivers have managed better than average yac (15th yac, 8th yacoe), which helps him get decent yardage (12th ypa).
He faces a bit higher than average pressure (15th pr%) and responds by taking sacks (5th sk%) instead of throwing the ball away (21st ta%). That brings his net yardage efficiency below the average QB (19th ny/d).
He turns the ball over a lot (9th to%) and doesn’t throw/scramble for many TDs (21st td%), but he does manage to move the chains (8th 1st%).
His overall efficiency is a bit above average (16th epa/d), but his success rate on plays is very high (6th psr) suggesting the big plays tend to go against him ( i.e. turnovers instead of TDs).
