Developing Down and Distance Data

How to break down the D&D data.

Down and Distance (D&D) seems easy enough, right? As the offense moves along the field, their play calling is predicated on the down (how many more plays they have left to get ten yards) and the distance (how many yards they need to get so they can start over). It is a very simplistic stat, but it has major ramifications on how offenses call their plays. Looking at the D&D stat from a simplistic eye will give a defensive coach a wide range look at how often a team runs or passes on a given down. Add personnel groupings and the data begins to get clearer.

2nd-down-markerjpg1428337613141.jpegIn order to truly get a grasp of what an offense is doing you have to create D&D groupings for long (7+), medium (4-6), and short yardage situations (1-3). This can allow a DC to pinpoint what plays are more likely in situations, allowing him to call the correct blitz or pressure at the right moment. Defense is reactionary, thus needs to react off the data that is provided by particular stats, in this case, the D&D. Pundits and coaches say it all the time, football is a situational game. The chess match that is football attests its strategy on several factors: field position, D&D, and what personnel grouping are on the field. Branching from that, formations and run/pass stats. For the sake of this article, MatchQuarters will discuss the breakdown of D&D and talk about the intricacies of each grouping. To understand completely what an offense is trying to do, the D&D should be looked at objectively with field positions groupings. The two data points combined give a true glimpse into the mind of the opponent’s OC.  Continue reading “Developing Down and Distance Data”

Throw Out The Stats

Five ways to judge a defense.

“Some teams will play 55 snaps today. I think we defended 17 possessions, 110 (snaps), so we just played two ball games… That’s why the yardage thing is so irrelevant.”

– Glenn Spencer/DC, Oklahoma St. | via Kyle Fredrickson, NewsOK.com.

It’s time for defensive coaches everywhere to start changing the way they view modern defensive football. The “spread movement” is real, and it is not going away. The spread scheme, though vast in its styles has one basic principle, create one-on-one matchups by using the entire width of the field. Adding tempo to spread schemes creates more possessions and opportunities to score points. It is not uncommon for college teams to run 90+ offensive plays in a game or a high school offense to reach 75-80+ plays. As the amount of snaps being played in a game increase, it puts more pressure on the defense to line up correctly and play every snap. Most teams in the Big 12 will play a half game or more each week compared to its SEC counterparts. As Glenn Spencer stated in the quote above, the yardage stat is becoming less relevant than ever before. To gauge how great a defense is in the modern football era defensive coaches and pundits everywhere need to readjust the standards for what makes a great defense.

Five Points of Emphasis

Points Per Possession

Conditioning against tempo teams is a premium for the defensive side of the ball. More possessions create more opportunities for points, thus more opportunity for mistakes. Spread teams operate by creating one-on-one matchups and “spreading” the field to create space. As more spread teams implement tempo and gain more possessions, the old stats of yards per game and points per game become irrelevant. If a team gives up 28 points and defends 8 possessions (3.5 PPP), are they better than a defense that gives up 35 points but defends 15 possessions (2.3 PPP)? Defensive coaches need to be less infatuated with yards and points. The only points that matter are the ones needed to win a game. The PPP stat evens out teams that play spread versus teams that play traditional huddle-up offenses. If looking at the PPP stat, one can better determine the strength of the defense because it focuses on how many drives turn into scoring drives. A drive is a drive, the difference is how many did a team defend, and did it give up some points? A good number for a defense is anything under 2 points, elite is under 1.5.
