All the different stats available today in the age of analytics can be exhausting! We will explore five statistics in the NFL today that should be used more when discussing player performance. Some stats are overplayed while others deserve more attention. Here are my five underrated important statistics:
1. Air Yards per Completion
Quarterback stats are too quick to anoint players as great when a little more in-depth analysis is required. The classic “dink-and-dunk” quarterback with a lot of yardage but also a lot of attempts or completions is not great in my opinion. Air yards per completion is useful in evaluating quarterback play because it is a way to evaluate efficiency. While we describe below that a team should pass on first down, and that’s likely a short, high-percentage pass, other plays should stretch the field and move the team in chunks down the field. Air yards per completion shows an open playbook and a quarterback’s willingness to stretch and utilize the entire field forcing the defense to cover every inch of grass.
2. EPA – Expected Points Added
This is critical to understanding what happens when teams start with bad field possession, get behind on downs, how much time remains in a half and what we can expect from an opponent when the ball is turned over or punted. It is the addition of all these outcomes and predicts how lethal a team is when on the field. Generally, teams excelling with a higher EPA are more fundamentally sound in special teams, stay in first down or short distance to first down, don’t turn the ball over often and possess the ball for much of the game. A team that plays smart special teams and has good field position starts with a likely advantage to score. Now add in avoiding third down or long distance conversion situations, high time of possession and little turnovers. This leads to high expected points and likely a recipe for success!
3. % of Pass/Rush Play Calls on 1st Down
With the statistic we just discussed EPA, there’s a clear sequence that directly leads to a higher EPA and therefore a higher likelihood that the team will score. Pass-rush-rush or pass-pass-rush are the most successful but many NFL teams have the archaic thinking of rush-rush-pass. The issue lies in that the average rush in the NFL is around four or four and a half yards. Rushing on first down using this average will automatically put you behind in a second-and-long situation. An average completion in the NFL is over eight yards. Taking just the average, a team has already set itself up for a second and short situation. Quite simply, teams with higher percentage of early down passes usually have more efficient offenses and better records.
4. Rush Yards Before Contact/Attempts
A statistic shown in more detail on profootballreference.com. This stat is an easy way to show how competent an offensive line is performing and also how schematic an offense is at disguising run plays and utilizing leverage on the correct side of the field. Running backs need space and running lanes to be efficient and succeed. Some running backs are talented breaking tackles and bouncing off contact. However, putting them in space and avoiding contact as long as possible is the successful method.
5. Time Of Possession
I don’t think there’s enough emphasis on time of possession and how debilitating it is to an opponent’s defense. According to this study, every additional minute an offense possesses the ball, the team’s chance of winning goes up 22 percent. Now this page goes on to argue Chip Kelly’s point that it doesn’t matter. However, defensive players show exhaustion much quicker than offensive players. Running a significant number of plays and holding the ball generally leads to victory. This may not be apparent in the first half of a game. Later on, it will grind a defense down and an offense will move at will if winning the time of possession.
