Playbook Confidential: Chargers Bye Week
I want to start everyone off during this bye week with an XTRA 1360 World of Sports interview of Norv Turner that really brightened my day last Thursday. If you don't have fifteen minutes to listen, then at least skip to the 12:20 mark for the last three minutes, which were fascinating. That was the part where they used a question that I had submitted via twitter!
Q: Do you have a name for the package when Mathews and Tolbert are on the field at the same time, and is that something we could see more of as the season goes on?
Norv Turner: Well, really the reason we've done it, it really has more to do with our tight ends because they've been beat up and obviously Randy McMichael has played an awful lot of snaps... but what we do actually when Ryan and Tolbert are in the game together, we actually put Vincent Jackson in the slot and play with three wide receivers. People have played coverage to Vincent and it gave us some opportunities to get a couple runs and get some passes to the backs but obviously the reason we're doing it is to try to get another receiver into the game and get the ball up the field a little bit more. Yeah, we're going to use it... we number our personnel groups, it's "20" which means two backs in the game and no tight ends so that's the personnel group. They bounced around a lot of names, the players, they find a lot of different names that I probably couldn't mention them to you on the air.
Q: These fans call us every Monday, they want to know why you run off tackle on the first series of every game. Could you just give me an answer to give them please?
Norv Turner: Well I know people look at those plays and say they are up the middle or off tackle, they are different plays... we actually have had decent success... I think every team, every situation, every team you're playing you have a plan that you're trying to put together and I don't put a lot of stock in, I don't think you're going to win the game or lose the game on the first play of the game. We've actually had a couple times this year where we've had a pass and a run checked, and we've gone to the run because that's the look we got. We're not against throwing the ball in any situation, usually people are complaining that we're throwing the ball too much so I guess I'm encouraged that they don't like the run on the first play of the game. We spend a lot of time obviously, putting the entire thing together. Sometimes it isn't the run that's the issue, it's the formation we're in we want to see how they're going to play us, sometimes it's a personnel group, we want to see how they're going to match up with a personnel group and I guess early in the game you are kind of getting a look at the other team and seeing how they're going to match up to the things you're doing.
Well that pretty much sums up JKvandal's writeup of personnel and play calling doesn't it?
So far through five weeks we've seen 351 plays run by the San Diego Offense. This is a passing team that runs the ball 40% of the time. They use shotgun 46% of the time, and a fullback on 24% of plays. First down is about a coin toss between run and pass, 2nd down shows a 33% chance of run, while 3rd down runs only ever happen in very specific circumstances. They've attempted to convert three 4th downs, and failed on all three tries. Keep that in mind next time you're screaming for Norv to take a chance!
| Down | Run | Pass | Total |
|---|---|---|---|
| 1st | 89 | 75 | 164 |
| 2nd | 36 | 77 | 113 |
| 3rd | 11 | 60 | 71 |
| 4th | 2 | 1 | 3 |
| Total | 138 | 213 | 351 |
So far, runs to the left have been the most successful, with the middle being the most popular choice. There's some fuel for the Sign On SD Clary haters club in there somewhere.
| Rushes | Average | |
|---|---|---|
| Left | 31 | 6.4 |
| Middle | 83 | 3.7 |
| Right | 24 | 4 |
It's also the case that the closer they get to the end zone, the more likely they are to run. I'm not sure if this is some universal thing that all offenses do, the way defenses are playing the Chargers, or if this is Norv's vanilla.
| Area of Field | Run | Pass |
|---|---|---|
| Own Half | 39% | 61% |
| Opponents Half | 40% | 60% |
| Red Zone | 49% | 51% |
| Goal to Go | 62% | 38% |
Let's next take a look at the running back playing time distribution. It might seem like Mathews runs the ball a lot more, and he does, but it's not like his presence is the massive run tell I was worried it could become. It's more that Tolbert gets a lot of his playing time in very obvious passing situations. I think this table shows that Norv is managing a platoon near perfection; maximizing specialties without giving too much away, while distributing wear and tear. Mathews is coming on strong, but still can't get the third down, goal line, or two minute drill job from away a healthy Tolbert. MOAR 20.
| Halfback | Snaps | Running Plays | Passing Plays | Run % | Playing Time % |
|---|---|---|---|---|---|
| Mathews | 186 | 86 | 99 | 46% | 53% |
| Tolbert | 149 | 40 | 109 | 27% | 42% |
| Hester (as HB) | 24 | 12 | 12 | 50% | 7% |
I drew up this table looking to see where our first downs come from in terms of originating down. The offense has a baseball-like overall .300 batting average for any given play to result in a first down. Hey, I warned you I was going all beautiful mind on this one.
| Down | Total Plays | First Downs | Conversion Percent |
|---|---|---|---|
| 1st | 164 | 36 | 22% |
| 2nd | 113 | 34 | 30% |
| 3rd | 71 | 37 | 52% |
| 4th | 3 | 0 | 0% |
| Total | 351 | 107 | 30% |
There hasn't been a blowout in either direction for the Chargers yet this season, so playcalling has not seen much in the way of garbage time. Playing with a tie most closely matches the overall run/pass balance. The team still favors the pass when leading, although not by much.
| Run | Pass | |
|---|---|---|
| Tied | 39% | 61% |
| Leading | 48% | 52% |
| Behind | 31% | 69% |
Next we'll look at the Personnel groups used overall. There's nothing shocking in these next two tables. There are really four workhorse groupings and then a bunch of gimmicks. "12" is the most popular group, with "11" next in line, then the fullbacks at "21 and "22". "22" is a guaranteed run while "11" is a guaranteed pass. Can anyone find some keys to predicting run/pass out of "12" or "21"? Just like last week's individual game against the Broncos, "12" asserts its dominance on 1st and 2nd down, but gives way to "11" on 3rd down.
| Personnel | Run | Pass | Total |
|---|---|---|---|
| 10 | 0 | 1 | 1 |
| 11 | 16 | 93 | 109 |
| 12 | 49 | 70 | 119 |
| 13 | 7 | 2 | 9 |
| 20 | 2 | 6 | 8 |
| 21 | 31 | 35 | 66 |
| 22 | 30 | 5 | 35 |
| 23 | 2 | 1 | 3 |
| Personnel | 10 | 11 | 12 | 13 | 20 | 21 | 22 | 23 |
|---|---|---|---|---|---|---|---|---|
| 1st | 0 | 34 | 65 | 5 | 2 | 36 | 21 | 0 |
| 2nd | 0 | 27 | 40 | 4 | 5 | 28 | 8 | 1 |
| 3rd | 1 | 47 | 14 | 0 | 1 | 1 | 6 | 1 |
| 4th | 0 | 1 | 0 | 0 | 0 | 1 | 0 | 1 |
Some more random bullets:
- 12 is the most likely setup for play fakes (still only 15%), and most play fakes are with Mathews (hat tip to Derek Snyder!)
- Mathews has more snaps than Tolbert in the 1st, 3rd, and 4th quarters (roughly 60%/40%), but for some weird reason, Tolbert owns the 2nd quarter by a significant margin (60%/40% the other way). I think this is because they have had a lot of end-of-half two minute drills and no end-of-game two minute drills.
- Out of 351 snaps, only 30 have had more than 10 yards to go. That's pretty mistake free football. Most of those greater than 10 to go plays were on 2nd down, making the majority of screw ups on 1st down. Thirteen out of seventeen (non penalty related) negative plays were lost yardage on runs.
- Options for trickery and more wrinkles that I think Norv has in his bag of tricks include: MOAR 20, more four wide, handoffs to WRs, LT-style halfback pass (never to Rivers though), and Crayton Wild-whatever-his-mascot-was. He's also definitely marinating something with the weird reverse wishbone he's run twice (once each the last two games).
- Eighteen shotgun runs have yielded 6.1 YPC. Ok, add shotgun runs to the list in the previous bullet.
- I couldn't really come up with any scripting patterns to game-opening drives, other than the fact that they are definitely making sure to get at least one look at the three major personnel groups ("11", "12", and either fullback group). Two of five game opening drives were three and outs. The other three moved the ball some, but none scored TDs. They are more inclined to run (50%/50%) on that first drive than the rest of the time as well. Somebody find something...please!
- MOAR 20

Crayton Wild-whatever-his-mascot-was
He was a Ranger
So it would be the Wild Ranger. Not too bad
6/10/2010 - Tra Thomas signs with the Chargers
8/21/2010 - Tra Thomas retires.
That was fast.
Not to be confused with the
Power Ranger
6/10/2010 - Tra Thomas signs with the Chargers
8/21/2010 - Tra Thomas retires.
That was fast.
So if I was a defensive coordinator...
I would game plan a shill first drive defense against Norv – then change it up early before making additional half time adjustments.

Wow, very comprehensive analysis Orz!
Rec’d
My best guess as to why Norv would try to run it the closer they got to the goal line probably has more to do with the fact that running is typically (league wide) more efficient in short yardage situations than passing. That stat combined with Norv’s “vanilla” offense (Efficiency over trickery) is my guess as to why that run total is so high close to the goal line.
If I were Norv
I would run a play action pass on our first goal line opportunity coming out of the bye week.
But there’s probably a pretty good reason I’m not Norv.

and because
gates has been out. We’ll have to see if gates can play and if so, if they run as much with him in there.
The first drive is well mixed
between formations and either run/pass probably for the exact reason that norv stated, “we want to see how they are going to play us.” The second drive is probably also like this.
I hate scooter pie
I found some stuff, but it's going in my post cuz I'm greedy like that!
Great work on the bye week post, I love how you hit on mistake-free football as that is one of the major focus points in my post that is scheduled for tomorrow.
I somehow feel vindicated at some of Norv’s comments, and I’m glad his system isn’t wildy different from the one that we are trying to analyze…at least as far as nomenclature.
I’m not sure if I truly believe that the sole point of 20 personnel is to take some snaps away from the TE’s, I think Norv was trying to shy away from that one and not give away much…because the majority of the 20 personnel that we see is with Tolbert/Mathews and Hester is typically not in there. Hester would be in there much more if he wasn’t truly trying to get both Mathews and Tolbert on the field at the same time…which is much more deadly with Jackson in the slot.
Also excited to see what this team can do in the shotgun run game…I think that is the new element that will burst onto the scene in the NFL once coaches catch up to the players. Many of the players coming into the league now have been in some sort of spread offense that often had run plays from the Shotgun formation, and probably calls for some different blocking schemes and I think players are ahead of the coaches in that facet…but I also stole some ideas from this article. I guess I’d just like to see the Chargers get out in front of the trend in that part of the game since they are already so deadly from 11 personnel, particularly shotgun…getting a solid run game from 11 personnel would make it nearly unstoppable (and less predictable).
Yeah I'm a big fan of Pat Kirwan
there aren’t many ex-GM’s writing articles and it brings an interesting perspective on things…also a huge fan of his book, and I would definitely not be writing “Playbook Confidential” articles without having read his book twice
I second that
That book is a great read. Still waiting to see if his prediction of Larry English’s projections pan out though.

*Can anyone find some keys to predicting run/pass out of "12" or "21"?
I took a stab at this. I looked at run/pass percentages for these personnel packages and compared them to the overall run/pass percentages.
In the Shotgun, run percentage is way up (+80%) in either the 12 or 21 personnel package, but still only 20% run vs. the overall 11% shotgun run percentage so it’s not like they’re running wild.
Here’s the Run Percentage variance for the 12 by Quarter and Down:
12:
By Qtr:
1 +20%
2 +12%
3 – 6%
4 – 7%
By Down
1 -12%
2 +33%
3 -54%
And the 21:
By Qtr:
1 +19%
2 – 3%
3 – 6%
4 +40% (small sample)
By Down
1 +23%
2 -56%
3 (insufficient data)
It looks like the Chargers are more likely to run in the first quarter with either of these packages.
- 12 on 3rd down is almost always a pass.
- 21 on 2nd down is predominantly a pass.
Maybe I’ll take another pass if I get the chance.
