ILBs and the 3-4 defense (1 Viewer)

Jene Bramel

Footballguy
Thanks to the questions and issues raised by Rovers and DonFue in other threads, I’ve been taking another look at the 3-4 defensive schemes around the league, and in a more detailed and systematic fashion than I confess I did at the beginning of 2006 when I first joined the staff.

If you don’t care about scheme issues or don’t think predicting which ILB in the 3-4 is the better IDP option is valuable information, stop reading now. :P The upshot of the rest of this post for you is that there is no reason to believe that Patrick Willis cannot become an absolute stud in San Francisco, despite what some would have you believe about all 3-4 ILBs.

For the rest of you who have closely followed my ramblings on the 3-4, it appears, after beginning to look through Gamebook data (correct and incorrect), playbooks, coaches’ quotes and discussion, and some old discussions I’ve had with the Guru himself (Norton), that I have been working under some faulty assumptions and conclusions. Some were correct anyway, some were not.

I’ve still got some research to do and am hoping to present a cleaner, clearer and hopefully useful article about the evolution of the 3-4 and its IDP implications later this summer. But, since there seem to be some clear trends that are different than what I’ve presented in the past, I felt I should post the short version here for those who have interest and begin to set the record straight.

So…the short version. And yes, as you’ll see this summer, this is the short version.

There are two major 3-4 defensive philosophies. Sparing you the historical and X and O details, one branch of the tree originated from Bum Phillips and was modernized by his son Wade, the other branch got its professional start with a couple of Patriot coaches who influenced Bill Parcells, Bill Belichick, and, indirectly, the Steeler coaches of the early 1990s.

Below is the raw data from 2002-present that I’ve collected from the FBG/Drinen database. There’ll be more data from before 2002 to be presented in the coming detailed summer article.

* denotes more than one tackle per game difference over 16 game seasonWade Phillips and assistants (incl Mike Nolan, Ted Cottrell, Greg Manusky, Brian Stewart):________________________LILB_______________RILB_____________2006 Chargers 57 *1002005 Chargers 66 *1142005 Niners 66 *992004 Chargers 73 *1052004 Ravens 56 *1012003 Falcons 103 *1262003 Ravens 68 *1212002 Falcons 75 *1112002 Ravens *125 104Bill Parcells:________________________LILB_______________RILB______________2006 Cowboys 66 642005 Cowboys *73 55 Dom Capers/**** Lebeau:________________________LILB_______________RILB______________2006 Steelers *85 622005 Steelers 87 762005 Texans 83 822004 Steelers 68 532004 Texans 80 *982003 Steelers 94 812003 Texans 101 1072002 Steelers *55 372002 Texans 100 96Bill Belichick hybrid and assistants:________________________LILB_______________RILB______________2006 Browns *100 762006 Jets *99 672005 Browns 89 772004 Patriots 75 642003 Patriots 82 67Conclusions (so far):1. There seems to be absolutely NO QUESTION that an ILB can produce big tackle numbers, regardless of how good the defense or player in question is. While it appears that only the Phillips’ scheme will produce a stud ILB, I’d caution you to wait for the pre-2002 dataset to be completed. I’ll guarantee that you’ll like the stats for some of Parcells’ ILB from the mid-1990s.

2. The Phillips scheme favors the RILB (weak side ILB). Without getting into the scheme stuff, that makes sense when looking at a playbook from a team that runs the system. Assuming there aren’t other issues, i.e. the RILB sits on passing downs, this should be reproducible moving forward. I hope to further confirm this when I complete the pre-2002 database.

3. The traditional non-Phillips scheme (Parcells/Steeler) doesn’t appear to favor either the WILB or the SILB. I don’t trust this data set completely, however. Parcells has been quoted as saying the WILB is the guy he expects to make tackles in his 3-4 scheme so I suspect this group will get muddled when I include data from the Jets and Giants pre-2002. My guess today is that this group will prove to be team and player dependent given a quick look at playbook and coaching notes.

4. The Belichick hybrid data may favor the LILB/SILB. If the gamebooks are to be trusted, both Andra Davis and Tedy Bruschi have seen significant drops in solo tackle stats when moved from the LILB to the RILB in recent seasons. And I just can’t grasp any other way that Jonathan Vilma gets out-tackled by a pair like Eric Barton and Brad Kassell. I suspect that the LILB is the MLB whenever these teams run a 4-3 and that’s an important reason for the difference in most cases since Belichick comes from the same branch Parcells does and uses the same defensive line scheme. Still, given the fact that the data set for the Patriots over the past two seasons is very unreliable due to the frequent 4-3 in 2006 and the multiple injuries in 2005 and 2006 to the ILBs, I don’t know that I’m willing to come to a firm conclusion on this group yet.

5. The Gamebook data, as we know, are not trustworthy. Unfortunately, while I apparently had recognized that Donnie Edwards was the RILB in the past when researching old posts, I didn’t recognize that the 2006 Charger gamebooks listed Edwards as the RILB, whereas the 05 and 04 suggested he played to the strong side. Given the coaching comments with regard to the Edwards/Godfrey – Wilhelm/Cooper deal recently, it seems clear that Edwards was the Mike LB/WILB. More unfortunately, a lot of my “take the LILB” thoughts derived from Edwards’ stats and a reasonable conclusion that the strong side player would get more opportunity as teams run to that side more often. Lesson learned. Although I don’t know that it’ll end up being a killer mistake, apologies to those who rostered Stephen Cooper over Matt Wilhelm last year on that advice. If it’s any consolation, I’m heavily invested in the wrong stock too and I think the detailed research I’m doing now will put us on the correct track moving forward.

6. While I panned DonFue’s comment suggesting that you draft the better player as a default as not well reasoned enough, it’s clearly not a bad way to go after a closer look at the non-Phillips playbook. My early thought is that his recommendation to take the better player is legitimate if there are no coaching comments or nickel considerations in the non-Phillips teams. I’d still like to see more data on the Belichick teams, though, as that certainly wouldn’t have worked in the Vilma situation.

--------------------------------------------------------

Again, the PRIMARY IMPLICATION for 2007:

Patrick Willis has every chance to be a stud right now. The data set for the Phillips 3-4 over the past five seasons, playbook considerations and comments from the relevant coaches all point strongly to his having plenty of opportunity this season.

Finally, I’d prefer that your projectiles be tomatoes rather than stones. :bag:

interesting. my feeling was always that the RILB was the more valuable player to have but I hadn't looked into it that closely and figured maybe I was wrong after reading a lot of your posts on the subject. from what I remember while watching the Bills defense under Wade Phillips, there was always one ILB who needed to be strong and willing to sacrifice himself so that the other guy could roam more freely and make plays. As a result, John Holocek used to take on a lot more blockers to free up Sam Cowart. I figured the ILB playing closer to the strong side of the formation (LILB) would be the one more likely to get caught up in trash, taking on guards and fullbacks, etc. while the RILB could frequently swoop in unblocked and get the tackle. I thought the Pats ran things similarly with Ted Johnson taking on blockers to keep Bruschi free to make plays.

Jene... incredible effort here, and I can't imagine the time it took to get this data set put together. I'm freakin very impressed, my man! :unsure:

As for what I had said earlier on this topic... I'm very much a seat-of-the-pants guy. Heck, I don't even have Excell! I said I didn't think that Vilma's numbers would change all that much if he were moved to the other ILB spot. When I form an opinion, it's based on a culmination of inputs. Watching training camp, seeing how the flow is when the defense reacts, and I end up with a sort of combined gut feel/stats driven "just what I think" sort of mentality. I'm really bad with specific X's and O's conversations and number crunching. I don't even know how to use the data denominator! having said that, I've learned to trust my instincts when it comes to the Jets.

I don't think you needed to do a mea culpa here at all. For the most part, you had it right. These various coaching trees that run the 3-4 are different. Each can favor one side or the other, but the bottom line in each scheme is that the best LB will generally put up the better numbers if he's LILB or RILB. But, that can't be a good generalization either. Look at the NE situation. However, is Bruschi clearly the best ILB on that roster? That's when which side he's on becomes a bigger determining factor imo.

With Vlima, it's clear he hasn't adapted to Mangini's 3-4 yet. That is one reason why I don't believe moving him from the right to the left would impact his numbers much, in large part. I also don't believe that Donnie Edwards is THAT much better than Vilma is in a 3-4. Stats wise, yes... but not on the field of play. I refuse to say that Donnie Edwards is a better LB than Vilma is. I think each player's responsibilty in the team defensive concept and what assignments each has even on a game to game basis has more impact on their FF numbers than how good they are on the field within each scheme. No, I don't have data to support my opinion...lol... and maybe I never will!

I said I would do something this year.... I will catalog every single defensive down of every Jets game, which LB's are in, where they line up and which subs are in. Kassel spelled Vilma more than you realize. Based on memory, I'd guess that 40% of his snaps came from Vilma's spot. So, I don't think it's accurate to add Barton and Kassel's numbers and then compare them to that of Vilma's. I' won't swear to that however, which is why I will catalog all of the Jets games this year, and give you that info, raw as it may be to work with.

In any case.... I think you had it mostly right. I also believe that Willis is likely to be the stud most think he will be.... but I'd still draft Poz ahead of him (assuming he is a 3 down MLB in the Buffalo scheme), just because that seems like a more sure bet. Once your finished, there will be much less doubt about scheme and FF studliness.... no doubt about that... THAT's a SURE bet!

 
You just made very uncommon knowlegde common. I'm still slightly skeptical of Conclusion #2 b/c the better player played RILB but that's chicken-or-egg crap. Nice work. Now delete it!

 
Nice Jean :popcorn:

Back in the late 80's in the Parcell/Belichick era, , Carl Banks put up nice numbers, I think he was the top IDP one year in our league, can't recall if he played inside or out now. Mills played ILB in New Orleans and scored well as did Pat Swilling & Ricky Jackson (OLB). Think Mora was the coach, and Wade Phillips was the DC.

Banks was an interesting case. The mid-80s Giant team will be tough to datamine. Banks apparently played inside in the nickel package and outside (mostly) on rushing downs. I'm not sure that data will be useful, but it may be.There's going to be a lot of good data from the pre-2002 years though. Levon Kirkland, Shane Conlan-Cornelius Bennett, Sam Cowart-Marvin Jones-Pepper Johnson, Sam Mills, etc. Lot of very, very good ILB to compare. Hopefully, I can find enough reliable depth chart and biographical information to slot them in their correct roles.

Thanks to you, I'm a little skeptical of the whole 3-4 thing too. :pickle:Still, there are playbook considerations with regard to the Phillips 3-4 that make me think that the RILB will be solid no matter how good the LILB is in that scheme.Letting the cat out of the bag is part of what we do here at FBG I guess. If it makes you feel much better, I doubt I'll get the rest of the research done before the free content date cutoff. Since I've run on about the LILB issue, I thought it was important to present what looked like a clear finding in Willis' favor now.
 
I rostered Cooper - but he didn't cost a lot and I'll have to drop five players by the beginning of the season anyway.

I forgive ya, Jene

ETA: Willis went the pick before mine and I grabbed Posluszny, so either way I'm good

This would be very valuable information. It would go against some of the beat writer observations from last year, but given all the poor information coming from most everyone connected with the Jets media last year I'm not real confident that they were accurate anyway. :pickle:

Part of that was because they weren't too happy with Schlegel's development. I should have saved my game tapes... oh well.

I rostered Wilhelm because Cooper was gone. You never know how things will play out. I'll have to drop more than five but right now many are wildcards. Including Wilhelm.
 
Jene, you probably already know this but Goodell has put in place a new rule mandating that teams maintain up-to-date and accurate depth charts on their websites. The Jets, who are the focus of many of these discussions, are one team that is notorious under Mangini for not doing this in years past. This may prove helpful to you.

[carson]I did not know that.[/carson]Thought the issue was primarily with the injury reports.

This is great news, not only for us IDP geeks, but it should make a lot of commish lives much easier in expanded IDP leagues.

Below is the raw data from 2002-present that I’ve collected from the FBG/Drinen database.
Wait, Doug has IDP data? Is this available for download at PFR?
Drinen is the generator of nearly everything in our FBG database. Our statbase goes back through 2002 on the player pages. That's what I was referencing.To my knowledge, Doug isn't currently working on plans to include those stats on his website.

I find that kind of funny. Mangini after one year is "notorious"? (from the link)It never was a point of being secretive for Mangini.... anyone who went to TC knew who the starters were.... at least once training camp battles were fought over, and won or lost. Mangini wants to avoid "annointing" players as starters.... that is to keep the competition going... keeping the starters on their toes, and keeping the backups hopeful of winning the starting job. He'll have to find some other tool in his tool box to keep percieved competition going between starters and backups now. Last year it was left to the Jets' PR dept to generate the depth chart. They got the starters right, but put the D in a 4-3 instead of a 3-4. That way, Mangini himself did not have to name starters. With the hiring of Randy Lange, ex-Jets beat reporter, that error was not going to be repeated by him as the new head of the PR and media dept.

+1I think we're on the hunt for the ILBs that are free to make plays, cause responsibilities and gaps change. Willis has a good shot to be that guy in SF. Derek Smith was taking on blockers at the end of the year while Brandon Moore was putting up nice tackle amounts. Willis is an upgrade over Moore
 
Thanks Jene.

Good read, and more importantly, you saved me the time to dig up all this information for Rovers about Nolan's 3-4 scheme and how Willis will be a stud this year. :shrug:
