Packing the Stats: Defense Tackling Improvements

Packing the StatsIn my recent perusal of the internet for some Green Bay Packers news in the offseason, I came across an article at Football Outsiders by editor-in-chief Aaron Schatz. “Broken Tackles 2012: Defense” focuses on the best and worst defensive players when it came to broken tackles last season. Those of us who regularly follow the Packers know that tackling was a big point of interest after an abysmal 2011 season when, according to ProFootballFocus.com, they missed a whopping 109 tackles.

Naturally, I was intrigued to see how the Packers and some of their individual players ranked among the rest of the league for 2012. I braced for the worst, knowing the defense was lacking against opposing rushing attacks. (They gave up 132.6 yards per game, for 25th in the NFL.) And then, of course, were the games against Adrian Peterson.

Imagine my surprise when I found out the Packers were in the top three best teams when it came to missed tackles.

Now, let’s clear something up first. Football Outsiders clearly defined their criteria for a “broken tackle,” which should not be confused with the PFF “missed tackle” statistic. (Though for comparison’s sake, the 109 missed tackles from 2011 dropped down to just 81 in 2012 as charted by PFF.) That aside, here is how FO defines a “broken tackle”:

Packing the Stats: The 49ers, Ted Thompson, and Draft Class Contributions

Packing the StatsYou know what’s been bugging me about some fans’ reactions to the 2013 NFL Draft? They look at the San Francisco 49ers, who have been lauded for their draft results, and feel like the Green Bay Packers’ selections were utterly underwhelming by comparison.

Yes, the 49ers had a great draft. They were able to get some highly regarded players who could definitely make their great team even better. But I have a few counterpoints to the assertion that the Packers had a terrible draft in comparison. First and foremost, the 49ers started out with thirteen picks to the Packers’ eight. According to the traditional trade value chart, San Francisco’s total value of picks was about 1,958 points, compared to Green Bay’s total value of about 1,318 points.

In other words, the 49ers started out with 48.6% more draft value than the Packers. Of course they’re going to be able to get more out of it!

Secondly, these players have yet to play a single down in the pro arena. We should very well know by now that high draft picks can be phenomenal busts, while low draft picks can be hidden diamonds in the rough. It’s worthwhile to compare draft value based on scouting grades and reports; however, it’s rather silly to make concrete future predictions based on that.

Packing the 2013 NFL Draft Stats: Explosion Number, Part 1

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:

BENCH PRESS (reps) + VERTICAL LEAP (in.) + STANDING BROAD JUMP (ft.) = EXPLOSION NUMBER

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.

Packing the 2013 NFL Draft Stats: Production Ratio

Packing the StatsI have a confession to make: I’m completely clueless when it comes to NFL draft prospects. Okay, well maybe not clueless, but I don’t follow college football, so it’s hard to really know much about these guys moving around the draft boards. Once a guy gets drafted by the Green Bay Packers, then I take the time to read up on his scouting report and check out the highlight reels.

That means you won’t be getting a lot from me when it comes to evaluating players. However, as we get closer to the 2013 NFL Draft, I’m going to post some statistics articles that relate to the current rookie prospects. The nice thing about statistics is that I don’t really have to be that intimate with the players’ individual skills and deficiencies. I can take some of their important numbers, crunch them together, and make something useful out of them.

Of course, this is where I make my disclaimer that statistics don’t tell the whole story. They’re a useful tool when evaluating performance, but they’re just one item in the toolbox. Just like the “measurables” from the NFL Combine and pro days, statistics need to be combined with the rest of the puzzle to make the complete picture. (Okay, maybe that was one too many analogies in a single paragraph.)

Packers B.J. Raji in 2012: Warrior or Shrinking Violet?

B.J. Raji 2012

B.J. Raji

From the time BJ Raji was drafted in 2009, I’ve taken a special interest in this player. Maybe because he’s from a local town here in NJ, maybe because I was hoping he would be one of the linchpins for Dom Caper’s new 3-4 defense – the next “Gravedigger.”

I wrote a profile on Raji back in May of 2009, and later talked to some people who saw him in his HS playing days. “Really nice kid from a nice family,” I heard repeatedly, followed by, not sure if he has enough “mean” in his personality to thrive in the trenches in the NFL.

I discounted those comments for the most part. Surely the Packers wouldn’t have spent a top-10 draft choice on him if the Packers didn’t think he was a potential star.

B.J. Raji made the Pro Bowl in 2011, probably based on the rep earned by his 8 sacks and strong sophomore season  in 2010 (film study here).  Ironically, though, he just wasn’t that good in 2011.

Raji’s 2012 season for the Packers was noticeably better than 2011, but one major thing was missing; consistency.  It seemed to these non-expert eyes that as the season unfolded, Raji had some very strong performances, and some downright awful ones.

Raji terrorized the Bears (film study here) late in the season and a few weeks later was bounced around like a pinball machine by the 49ers offensive line. With those two offensive lines being on opposite ends of the talent scale, a thought crossed my mind; were’s Raji’s “good” performances all against “bad” offensive lines and vica versa?

Packing the Stats: Is Aaron Rodgers’ Time Ticking Away?

Packing the StatsIn the shadow of the last two postseason losses, I’ve seen a number of Green Bay Packers fans itching for Ted Thompson to make some big roster moves. Their basic premise is that star quarterback Aaron Rodgers doesn’t have much time left to get to another Super Bowl. It’s either now or never if the team wants to make another serious run at it.

Rodgers is, after all, turning 30 this December. By the time the season is over and the playoffs are underway, he’ll have reached that magic age in the NFL when a player’s value suddenly drops like a brand new car being driven off the dealer’s lot. Sure, he hasn’t shown any physical or mental signs of decline in his performance, but time flies when you’re chasing the Lombardi Trophy.

To be perfectly clear, I have been a big skeptic of this line of thinking. This skepticism has actually led me to do a little data mining. How many quarterbacks have won the Super Bowl after they’ve turned 30? How many have even played in a Super Bowl? Is it a foregone conclusion that Rodgers will be battling the odds in the coming years?

So I went all the way back to Super Bowl XXX and compiled the ages of the starting quarterbacks since that year. Just to note, I only went back 18 years for the purposes of time management and the idea that modern rules are helping with durability. Quarterbacks are being protected from physically damaging hits, so they should theoretically have a better chance of playing into their later years.

Packing the Stats: Packers First Down Failures

Packing the StatsOne thing I noticed while watching the Green Bay Packers humiliating loss to the New York Giants was their inability to put themselves in favorable down-and-distance situations.

In fact, of the 54 offensive downs that Aaron Rodgers was on the field for, 40 of them were at or over ten yards to convert. Three were in the moderate-long range (7-9 yds.), eight were in the moderate-short range (4-6 yds.), and only three were in the short range (1-3 yds.).

But how does this compare with the rest of the season? It’s one thing to have the numbers, but we also have to have some context and comparison. After all, there will tend to be more downs of 10 yards to go, since that is what most first downs start with.

Without further ado, here is some raw data concerning the Packers’ offensive performance by down-and-distance (click on the image for a larger resolution):

 

2012 Green Bay Packers, Yards Gained by Down and Distance

 

The first thing to look at is the yards per play on first down. Green Bay had its lowest overall production on first-and-long this season (2.68 yards per play). Their second lowest output came against the Seahawks where they averaged a full yard more at 3.68 yds/play. Perhaps somewhat surprisingly, their best production on first-and-long came against the Indianapolis Colts (6.79 yds/play).
