Meet Our NFL Charting Team

Charters that work for Armchair are not just casual fans or college interns — they are a mix of data scientists, former professional players and fantasy football pro's who know the game inside-and-out.

They also have one important thing in common: they are all partners in the business and each and every one uses the data that we collect for their own endeavors. They have a vested interest in maintaining data quality and a desire to continually push the program forward with the addition of new metrics each season.

  • Hash Mark Location


    Where the ball is placed when the center has it in his hand. Values can be (L)eft hash, (R)ight hash or in-between (M for Middle).

  • Motion


    There are 2 types of motion: Pre-snap (P) which starts and stops before the snap and the more aggressive type of motion that is occurring during the snap (S). When both occur we mark 'PS'.

  • # Of Defensive Linemen


    Number of Defensive Linemen on the field.

  • # Of Linebackers


    Number of Linebackers on the field.

  • Number of DB's in the box

  • Trick Look


    Some obvious trickery is going on (0 - No, 1 - Yes). Usually it's a wildcat formation or when the QB lines up in a uncommon position. Fake punts and fake field goals are not trick looks since they look like regular punts or FG's.

  • Trick Play


    Fake punts, double passes, flea flickers, wildcats etc (0 - No, 1 - Yes).

  • QB Sneak


    Quarterback dives ahead directly off the snap for short-yardage. A high percentage conversion but these plays also open up QB's for some physical abuse.

  • QB Scramble


    Play design is initially a pass but QB elects to run based on pressure; a lack of open receivers, or, simply seeing an opportunity to make positive yardage running himself.

  • Time to Scramble


    Seconds elapsed between the snap and when the QB scrambles.

  • Physical Ball


    Pass target takes significant punishment whether the pass is caught or not. Most 'Contested Balls' will also be a 'Physical Ball'.

  • First Read


    QB passes to the initial receiver he looks at after the snap (0 - No, 1- Yes).

  • Pain Free Play


    Analyze which players are escaping long-term damage. These are cases where the ball carrier is only lightly touched by a defender on the field (ie QB slide) or runs out of bounds with little or no physical contact with the defender or sideline personnel/equipment. Includes TD's.

  • Time to Pass


    Seconds elapsed between the snap and when the QB attempts the pass.

  • QB Sack


    QB was to blame for the sack: held ball too long; missed wide open receiver etc (0 - No, 1 - Yes).

  • Time to Pressure


    Seconds elapsed between the snap and when the QB starts to feel pressure.

  • Time to Escape Pocket


    Seconds elapsed between the snap and when the QB escapes the pocket.

The Rest of the Line-up from 2019 (Pro Stats)

Number of Players in the Backfield

Number of Players in the Backfield


This is the number of skill players (WR + TE + RB) that lined up in the backfield on the play.

Men In The Box

Men In The Box


Is the offense facing the typical 'front 7' or are there some extra defenders looking to stuff the run? We chart this on both passing and rushing plays.

Play Action Pass

Play Action Pass


Play starts with what appears to be a running play, but turns out to be a pass play. We don't consider whether a defense was fooled or not, just that a QB motioned to the RB with the ball and some effort to sell the run occurred.

QB Pressure

QB Pressure


A Pressure is marked on a play where the pocket is breached and the QB is near the breach. Note: Most screen passes don't qualify and the QB also can't already be in the act of passing.

QB Hit

QB Hit


QB was brought to the ground or otherwise significantly man-handled. Almost all sacks are hits but hits can also occur after the ball has left. On rare occasions, hits happen without pressure but they usually go hand-in-hand.

QB Hurry

QB Hurry


A heavier form of pressure that essentially breaks a play. The QB is either forced to leave the pocket and improvise or throws the ball sooner than planned.

Hindered Throwing Motion

Hindered Throwing Motion


The Quarterbacks throwing motion was hindered in some way by a defender.

Number of Pass Rushers

Number of Pass Rushers


Total number of players rushing the passer.

Number of Blitzers

Number of Blitzers


Total number of LB's and DB's blitzing.

Number of DB's Blitzing

Number of DB's Blitzing


Number of DB's blitzing. This is included in the BLZ total.


Zone Blitz


At least one Off-Ball LB rushed the passer instead of a DL who dropped into coverage (0 - No, 1 - Yes).




When any two pass rushers cross, trading pass rush lanes on a passing down. (0 - No, 1 - Yes).

Out of Pocket Pass

Out of Pocket Pass


Quarterback attempts the pass out of the pocket whether pressured or not (0 - No, 1 - Yes).

Available Targets

Available Targets


Number of skill players (WR-TE-RB) running a route on the play. AVT does not determine whether the target was open or not.

Depth of Target Rank

Depth of Target Rank


The rank of pass targets according to distance in yards from the QB. #1 is closest to the QB. Targets are ranked at the point the ball is closest to the receiver.

Coverage On Target

Coverage On Target


Uncovered is 0, single coverage is 1, double is 2.

Contested Balls

Contested Ball


Passes into close coverage that involve a physical battle between receiver and defender for control of the ball.

QB Throw Away

QB Throw Away


Quarterback threw away the ball to avoid a sack or for lack of any open targets (0 - No, 1 - Yes).

Shovel/Touch Pass

Shovel/Touch Pass


Passes where the QB palms the football, and "shovels" the pass directly forward to the receiver, usually with a backhand, underhand, or pushing motion.

Sideline Pass

Sideline Pass


Balls outside of the field but catchable when the receiver extends body/arms.

Highlight Pass

Highlight Pass


A perfect pass that only the receiver can reach. Features perfect placement in a tight window.

Created Receptions

Created Reception


Opposite of a drop. Here the QB is being helped by a receiver making a difficult catch requiring exceptional body control; hands; acrobatics, or any combination thereof.

INT Worthy Pass

INT Worthy Pass


Essentially a 'bad pass'. An INTW is not always an INT, perhaps the defender muffs the opportunity. Also, not every INT is a INTW. One example would be a catchable ball bouncing off a receivers chest and into the hands of a defender.

Dropped Passes

Dropped Pass


Which QB's are being let down by their receiving core? A dropped pass is a ball that would have been caught by a receiver with league-average skills.

Passes Batted Away

Batted Pass


Balls batted away at the line of scrimmage (0 - No, 1 - Yes).

Screen Pass

Screen Pass


Screens come in many forms. A screen to a running back to either the strong or short side of the field in the flats is often just called a screen. Screens to wide receivers come in four forms: the bubble, middle, slot, and slip.

Missed/Broken Tackles

Missed/Broken Tackles


The ball carrier either escapes from the grasp of an unblocked defender, or the defender is in good position for a tackle but the ball carrier makes an athletic move (aka juke) to avoid the tackle.

Time to Sack

Time To Sack


We go beyond basic sack stats to find the exact number of seconds that elapsed from the time of the snap to when the sack occurred.

True Air Yards

True Air Yards


Distance ball travels in the air from point of throw to a receivers hands; back of endzone or sideline.

Depth of Target (Yards)

Depth of Target (Yards)


Distance from the line of scrimmage to where the ball is caught or comes closest to the target (endzone yards are also included).

Yards After Catch

Yards After Catch


The best receivers are thinking beyond the catch and what they need to do to extend the yardage.

Yards After Contact

Yards After Contact


Contact can be significant but also more minor in nature. We track this for both rushers and pass catchers.

Defenders on QB Pressure, Hurries, Hits

Defenders on QB Pressure, Hurries, Hits


Player codes for defenders involved in Pressures, Hurries and Hits. Pressures and Hurries may list DEFxx1 and DEFxx2.
