Packing the 2013 NFL Draft Stats: Explosion Number, Part 1 All Green Bay Packers All the Time

Packing the StatsA couple weeks ago, I presented some data in regard to some of the 3-4 defensive front prospects that the Green Bay Packers could be looking at in the upcoming 2013 NFL Draft. We calculated their “production ratios” based on big plays during their college years. This time around, we’re going to take some numbers from the NFL Combine to see how explosive some of these players are.

Taking another page from Pat Kirwan’s book, “Take Your Eye Off the Ball,” we’re going to take some of the combine measurable and plug them into a formula that will help to show how explosive these players are.

“On the snap of the ball,” writes Kirwan, “the front seven and the offensive line are going to engage physically. It’s a series of adjacent bar fights, and we need to be able to project who has the athleticism to win these all-important battles in the trenches. . . . A prospect with an Explosion Number of 70 or higher has my attention.”

So how do we calculate this number? Here’s the formula:


The bench press, vertical jump, and broad jump are three workouts at the combine that specifically test a player’s raw strength, power, and explosiveness. They comprise the core qualities that a defensive lineman needs to do his job. Other workouts like the 40-yard dash and three-cone drill don’t really factor into this equation, because they relate much less to these trench battles.

Without further ado, here are the numbers. The data is taken from NFL Combine Results, and the players listed are the only ones who have data for the required workouts. Some players skip certain workouts for health or preferential reasons, so their Explosion Number can’t be adequately measured. Additionally, I used to pare down the list to only those players projected as 3-4 candidates. The overall draft rankings are also based on DraftTek’s “big board.”

You’ll notice that only four players have an Explosion Number (EN) of 70 or greater: Brandon Williams, Cornelius Washington, Margus Hunt, and Nicholas Williams. None of them are projects as first round prospects, which is rather interesting; however, Datone Jones is extremely close with an EN of 69.8. Conversely, Ezekial Ansah is the highest ranked of the group, but only boasts an EN of 65.3.

Now, I also added my own personal touch to this equation. After looking at the players, it was clear that some of them were pushing around a lot more weight than others. Damontre Moore at 250 lbs. has much less weight to propel in the vertical and broad jumps than a guy like Brandon Williams at 335 lbs. To account for this, I adjusted the EN for weight so that heavier players got a little boost. Here’s what the equation looks like:


Basically, the vertical and broad jumps are multiplied by a ratio of the player’s weight to 275 lbs. In other words, a player who weighs 275 lbs. would have a multiplier of 1, while lighter players’ multipliers would be less and heavier players’ multipliers would be more.

You’ll notice that not much changes with the weight adjustment, though some players did get bumped. Brandon Williams is one example, though the biggest leap was by Georgia Tech’s T.J. Barnes.

As always, this is just one piece of the puzzle. Pure athleticism doesn’t account for technique, football intelligence, and mental quickness. Still, teams might feel they have a better chance of coaching up a physical powerhouse rather than trying to bulk up a weaker technician.

Feel free to share your thoughts on any of these draft prospects in the comments section below! And please check back in the near future for Part 2, where this formula is applied to offensive line prospects.

  1. It is an interesting metric and may mean something with some of these draft picks. The big thing missing is football sense. Having a big wingspan or explosive leap is great if you make the right move on the ball – otherwise, you put yourself out of the play in short order. Our game against the 49ers showed what happens to guys who don’t have high football IQ. Walden and Jones were constantly out of position and moving in the wrong direction on most of Kapernics options.

    I’ll take the analysis with a grain of salt.

  2. This kind of analysis is bordering on baseball-crazy! Although you have to like a stat that uses the word “explosion” in it. After careful analysis: [(destructive term) + (total number of letters) + (number of beverages consumed during formulation)]/(scrabble word score for term), this one clearly ranks in my top 5! 😉

    1. Just a piece of the puzzle, no doubt, but even if you’re missing just one piece then the final picture will have a hole in it.

      1. I’ve been liking Brandon Williams more than Jesse Williams, Kawann Short, Johnathan Hankins and even John Jenkins. Now I have even more reason to like him.

        If the Packers could get this guy with a second round pick it would be stealing.

  3. As always, Chad, love your analysis. (I’m a numbers guy myself). Like you say, just one piece of the puzzle, but certainly a piece you don’t get anywhere else.
    Keep it up!

    1. Any time you can combine football and Excel, I’m in! Now, if only you could figure out a way to add in some bacon…

  4. I really hope the Packers have a chance at Margus Hunt and TT jumps on it with both feet. 3 reasons.

    1. The guy’s pure athleticism is off the charts for a man of his stature. The last guy the Packers drafted with that kind of athleticism just signed a real big contract.

    2. As much as JJ Watt has emerged as a dispruptive force with passes defensed (16) and sacks (20.5) getting in a QB’s head, Hunt might surpass Watt’s numbers.

    3. I hear Estonians hate the last names Stafford, Cutler and Ponder.

    1. Hunt isn’t close to Watt. He is much taller and doesn’t play w good leverage. Unlike Watt… Tall too thin and poor leverage isn’t anything like Watt. Hunt might be OK in a 43 but not a 34 D.

  5. I took a look at the previous three drafts for explosion numbers. The top names:
    Jake Bequette, Jamie Blatnick, Andre Branch, Quinton Coples, Jack Crawford, Tyrone Crawford, Jared Crick, Vinny Curry, Justin Francis, Tim Fugger, Trevor Guyton, Malik Jackson, Jamaar Jarrett, Cam Johnson, Chandler Jones, Kentrell Lockett, Whitney Mercilus, Donte Paige-Moss, Nick Perry

    I’m not seeing a strong relationship here.

    1. 2009:

      Aaron Curry 72.3
      BJ Raji 73.6
      Aaron Maybin 70.3
      Brian Orakpo 81.3
      Brian Cushing 75.0
      Clay Matthews 68.5
      Evander Hood 76.0
