One of the funniest plays of the 2015 NFL season was Delanie Walker’s 61-yard touchdown reception against the New Orleans Saints.

If you don’t remember that play, it went something like this. Marcus Mariota dropped back in the pocket, having just returned from injury, Mariota was a little anxious in his movement. The Saints were able to get pressure on the quarterback, which caused Mariota to throw the ball downfield while falling backwards. His pass floated into the air and drifted high above the reach of Delanie Walker.

The ball drifted so high that Walker didn’t even sell out to try and catch it. Instead he positioned himself, expecting to be in position to make a tackle after a certain interception.

Mariota’s pass landed between two Saints defenders who, as Saints defenders did throughout the season, made fools out of themselves. Both defenders collided, causing the ball to bounce into the air for Walker to catch. The tight end ran in a long touchdown for Marcus Mariota’s stat line that should have been an interception.

Because Mariota’s mistake went unpunished, it was largely forgotten. It still lived on in the memory of some, but for comedic reasons rather than for the purposes of evaluation.

That is the type of play that is tracked in the Pre-Snap Reads Quarterback Catalogue. What is the Pre-Snap Reads Quarterback Catalogue? It’s a book that attempts to better separate individual quarterbacks from their supporting casts by analyzing players in great detail.

To write this book, I watched every snap that 35 quarterbacks took during the 2015 season. Any quarterback who attempted over 250 passes was included, as well as some quarterbacks of interest who didn’t.

Every pass attempt was charted as either accurate or inaccurate, those charts are included in each player’s individual chapter. While charting those throws, I tracked passes Interceptable Passes, Failed Receptions and Simple YAC.

Interceptable Passes are passes that should have been intercepted but weren’t because of defensive error. That Mariota throw immediately comes to mind. I first started tracking Interceptable Passes last year for the Interceptable Passes Project.

The process has been refined and the results have been expanded this year to further evaluate who is most prone to turnover-worthy throws.

Failed Receptions occur on passes where the quarterback throws an accurate throw but his receiver turns an accurate pass into an incompletion or an interception. It’s the same as drops, except the measurement has been expanded so that the aesthetic elements required for a play to qualify as a drop have been removed.

Receivers don’t have to have the ball bounce off of their hand to have a failed reception, they can show poor footwork by the sideline, misread the flight of the ball in the air or not control it as they fall to the ground. None of those plays would count as drops, but they would count as failed receptions.

Simple YAC only considers yards after the catch that are gained on throws where the ball doesn’t travel further than two yards past the line of scrimmage. The idea is to encapsulate every easy throw a quarterback makes, be they screens, checkdowns from the pocket or quick throws to uncovered receivers in the flat.

This section tracks completions, yards gained, touchdowns scored and how much each quarterback relies on those numbers through percentages.

After those three categories, the book looks at how each quarterback was sacked, tracking the primary reason for the sack and marking down which sacks could realistically have been avoided. Sacks are mostly measured by raw numbers or measured by the time elapsed for the quarterback to get sacked. Those are more rigid measurements but don’t tell you anything about the relationship between the quarterback and his protection.

Even if you break sacks down into the seconds it takes for the quarterback to hit, you’re not considering the design of the play, the number of rusher sent after the quarterback or the number of blockers in protection. Not least the route combinations downfield.

Once through all of the statistical analyses, the book turns to each quarterback individually and breaks down his season in greater detail, talking about why players put up the numbers they did or whether they were elevating or anchoring the production of their teammates.
