HOW WELL?
Through 4 weeks, Lamar Jackson has steadily improved his epa efficiency, but on the season he only ranks 19th best.
:format(webp):no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/22913085/02_QB_Tracker_Top_4.png){kind=tracking}
His passing success rate ranks 10th, his net yards per drop-back is 6th and his first down conversion rate is 11th, so the underlying drivers are good. It is his 4th highest turnover rate that is dragging down his overall epa.
HOW FAR?
His yards per attempt ranks 5th of all QBs and he has the longest average depth of completions in the league.

Here’s more evidence that he likes to throw far. He has the longest depth of target and the 2nd longest QB isn’t even close.

He doesn’t have a lot of TD passes (4), but they came from far away.

TO WHO?
Marquise Brown doesn’t have the most targets, but he gets the most yardage by far.

Watch out for the guys in the upper right quadrants.

HOW ACCURATE?
Lamar’s overall accuracy isn’t that good: he is only 21st in season cpoe.

HOW FAST?
With great depth of target comes great time to throw. His average drop-back takes 3.12 seconds, the 2nd longest in the league. Accompanying that is the 8th highest sack rate and 6th highest scramble rate.

DASHBOARD
:format(webp):no_upscale()/cdn.vox-cdn.com/uploads/chorus_asset/file/22913114/QB_Lamar_Jackson_Dashboard.png)
Jackson has led a balanced offense (18th ed%) with a strong run game (2nd wrsr) against less than average opponent passing defenses (20th opd).
He has the longest attempts (1st adot) and longest completions (1st ay/c) of any QB but to accomplish that, he holds the ball a long time (2nd TTT) which invites pressure (6th pr%) and results in a lot of sacks (8th sk%). His successful scrambling (6th scr%) counters that pressure and along with good receiver yac (10th yacoe), helps support his 4th best yardage efficiency (ny/d), which leads to the 11th best first down conversion rate (1st%).
The good news for the Colts is that he has less than average accuracy (21st cpoe) and has turned the ball over a lot (4th to%). He hasn’t thrown many TDs (24th td%) and his red zone efficiency is poor (21st rze). Overall, his long passes have been more miss than hit (24th 20+e)
