Around SBN: Raiders' GM Begins The Purge

Emerald Bowl Review: Part VIII: Know Thy Enemy

In this eighth part of a twelve post analysis, we're going to look how scouting can lead to a linebacker's recognition of the play.  In case you missed the previous installments, here is Part I, Part II, Part III, Part IV, Part V, Part VI, and Part VII.

Every team scouts their opponent.  They look at film.  They look for tendencies.  They look for substitution tendencies.  They look for formational tendencies.  They look for player tendencies.  Anything and everything is examined to see if the smallest tendency can be found to tip the play before the snap.  When a team goes bowling (to a bowl game), they have weeks and perhaps around a month to prepare for the game.  In that time, the team should be able to watch every single game of their opponent from that season.  When you watch that much film of your opponent, you get to know them pretty well. 

Prior to Cal's bowl game against Miami, I thought I'd do a quick scouting report on Miami.  Essentially, what I would be doing is a much much much smaller version of what the Cal Football team would be doing for Miami.  Without any film of Miami, I turned to Youtube and found some highlight videos.  I watched those videos and put together a small scouting report (Know They Enemy: Scouting the Miami Hurricanes).

One of the tendencies which I found was one of Miami's favorite passing routes.  In the YouTube video below of Miami vs. North Carolina, at approximately 2:40 into the video, Miami completes a pass to its slot WR on a mid-range (approximately a 15-18 yard) dig.  The "dig" is a route which the wide receiver runs straight up the field to a certain depth, then cuts towards the center of the field parallel to the line of scrimmage.  You can view the completed dig route at 2:40 in the video below:


Star-divide

I saw the very same route and completion on the highlight reel of Miami vs. Florida State.  You can view the dig route completion at 5:10 in the video below:


After seeing these two routes and completions out of similar formations and similar personnel packages I wrote:

5:10 - We saw these types of throws in the North Carolina footage.  Beware of the 15-18 yard digs from the slot WRs.  Linebacker interception opportunities if they read the route and the eyes of the QB.

Let's see how this plays out in the Emerald Bowl.  Below is the pre-snap picture:


8a_medium

Miami is in shotgun.  They have 11 personnel on the field (3 WRs, 1 TE, 1 RB) - not to be confused with 11 players on the field.  The TE is to the left of the offensive line.  I've put a red arrow by the Miami slot WR.  This is the man that the defense should be watching on plays where the offense is in shotgun with 3 WRs. 


8b_medium

Here's the post-snap picture.  The Miami slot WR runs his route as seen in previous games (red arrow).  The only slight difference is that in this play he's running his route slightly more at an angle to come underneath linebacker Zack Follett in coverage.  The purpose of coming underneath Follett is to "cross the face" of the defender to give your quarterback a target should the quarterback decide to pass the ball to you at that time.  Note that the Cal nose tackle, Hill, has dropped back to spy the quarterback.  A "spy" is a defender who is specifically assigned to watch the quarterback's movement and prevent the quarterback from scrambling for a gain.  Since Hill did not pass-rush, Cal has also sent two other linebackers (thus pass rushing 4 defenders).  The product of this act is what is called a "zone blitz."  A zone blitz is a play where defenders who usually rush the quarterback drop into coverage, and players who usually drop into coverage pass rush the quarterback.  Thus, on this play, the defenders who usually pass rush is Hill who drops into coverage, and the defenders who usually drop into coverage are the linebackers who pass rush.


8d_medium

As you can see in the picture above the Cal nose tackle is spying the QB.


8e_medium

The Miami QB passes the ball (highlighted yellow).  I've put a blue arrow on Cal linebacker Mike Mohamed.  He read the defensive formation, and the QB's eyes, and is eyeing the ball for his pending interception (green line). 

What did I say in my scouting report?:

Beware of the 15-18 yard digs from the slot WRs.  Linebacker interception opportunities if they read the route and the eyes of the QB.


8f_medium

Mohammed makes the interception!  I've highlighted the ball yellow.  I've also drawn in the defensive coverage and the WR route (Note: the boundaries of the zones are not absolute, I've merely drawn them over the yard lines to keep things easy for myself).  The WR route is in red.  The Cal defense was playing with two deep safeties each of whom covers the deep halves of the field.  Underneath the two deep zones, Cal had four underneath zones.  Cal linebacker Zack Follett, and Cal safety, Johnson, moved in for the hit after the pass (shown by the blue arrows).


8g_medium

And the Cal players rejoice!

 

 

Here's the video of the play.  (Special thanks to Ken Crawford from Excuse Me For My Voice, for volunteering to create youtube videos for the plays I am dissecting.)

 

 

Conclusion:

In only watching two short Youtube videos, I was able to pick up on a few of Miami's tendencies.  Now, just imagine how much more prepared the Cal defense was. 

This offensive play, or plays that are similar, were effective in previous games for Miami so it's not surprising that they were going to try and run the play in the Emerald Bowl.  However at the same time, it is surprising that they ran this play against Cal since it in involves a pretty dangerous pass over the middle of the field which is probably going to be against zones (such as in this play) because Cal likes to play zones.  A pass over the middle like in this play is going to have to involve perfect timing so the QB can pass the ball between the windows (the area between defenders in zone).  Furthermore, the QB cannot "lock onto" his target - meaning he immediately and only looks at the receiver he intends to throw to - because if the QB locks onto his target the defenders can read his eyes and jump the pass for an interception.  It's a safe bet that Mohamed not only knew prior to the snap that there was a possibility the slot WR on the other side of the field of him was going to run the dig towards him, but also that he was reading the Miami's QB's eyes.  Actually, scratch the latter half of the previous sentence.  Mohamed was watching the QB's eyes.  This is obvious in the youtube video above.  Note how Mohamed flows to his right as he follows the QB's eyes, then flows back to his left as the QB looks to the slot WR.

In summary, football teams watch film of each other to predict what the other team is going to do in certain situations or formations.  Watch a little film yourself, pay attention to what you watch, and you'll see the same  tendencies too.

nice write-up

Here’s a companion top-down look at the play progression (relatively unsure about Zack’s position because he’s out-of-frame). It was a fortunate defensive call, because Hill not rushing must’ve messed up the QB reading the coverage and, in turn, perhaps forced a little extra air under the ball so that Mohamed could get over in time to make a play by the fingertips.

Nice diagram, but...

It’s misleading. As Hydro pointed out, our defense was in zone coverage. Your diagram implies man coverage.

Dude how are you not working for the AD?

Question: is the spy typically the NT? Would it not be more prudent to have a more mobile defender act as the spy? Isn’t the NT just about the most ungainly player on the field when it comes to tracking down a sprightly QB?

Some say his powerade gives you infrared vision...and that his sweat towels wipe away sin. All we know is he's called giantfan5.

Haha. Typically, spies are linebackers and sometimes defensive ends. The whole point of having a spy is to counter a running QB. A QB that can run is usually a fast runner, thus you usually need a fast defender too. So yeah, most of the time you’ll see LBs spying the QB not a defensive lineman.

So why did Cal use a defensive lineman to spy instead of a linebacker? Well, Cal sent four men on pass rush (two linebackers: Holt and Williams; and two defensive lineman: Browner and Jordan), had one spy (Hill), and six defenders in zone. If Cal had used a linebacker to spy, that means instead of sending two LBs to pass rush, one of those LBs would drop back to spy (either Holt or Williams). To offset the loss of a pass rusher, Cal would probably then have D. Hill (who was the spy) pass rush instead to keep four pass rushers on the QB. Thus you have four men on pass rush (three defensive linemen: Hill, Jordan, and Browner; and one linebacker: Holt or Williams). But what is the product of this swap? A non-zone blitz. In other words, now the defensive isn’t zone blitzing. So the defense has lost the element of surprise of the zone blitz. In even more words, the OL isn’t as confused since the men they expect to pass rush (the DL) are all pass rushing. Remember, the whole point of the zone blitz is to confuse the OL by rushing defenders they don’t expect to pass rush (LBs, Safeties, CBs), and dropping defenders they expect to pass rush (the DL) back into zones and/or spies.

So in short, that whole complicated paragraph (which I hope you understood, sorry if you didn’t), means that if Cal had used a linebacker to spy, that the defensive play wouldn’t really be a zone blitz and probably would be less confusing for the OL and QB. However, Cal still might have gotten an INT, since Jacory Harris seemed to float his pass a little to get it over the spy. So in other words, it may not have mattered who was the spy, so long as somebody was spying to affect the throw.

formation

fantastic work as usual hydro. I have a question though – could you please explain what the defensive formation is? Since there are 4 linebackers on the field during this play (Holt, Williams, Follett, Mohamed), I would have to assume we’re in our standard 3-4 defense right? But the presnap pic shows 3 linebackers right up there on the line. Why do they do this? Are they trying to disguise who is rushing and who is going to drop back into zone? Also what are Cal’s tendencies regarding playing an extra CB (nickelback)?

Sorry if this seems like a noob question – I’m pretty new to all these concepts. Keep up the great work, hope to see more of these throughout the season!

The defense is still a 3-4 defense even though the linebackers aren’t in the traditional pre-snap location. By lining up the linebackers on the line of scrimmage, the defense is giving a more aggressive pass-rush look to the offense. The purpose of lining up on the line of scrimmage is also to confuse the offense by making them think six defenders are pass rushing (when it’s really four). In other words, the defense is disguising their defense. It would be rather obvious to the offense if the defense always pass rushed linebackers who were lined up on the LOS, and the linebackers who weren’t lined up on the LOS dropped into coverage. So the defense is mixing it up by putting most of the LBs on the LOS, and blitzing some and dropping others into coverage.

Also, since this is a zone blitz, and Cal is showing six pass rushing defenders pre-snap, Miami’s OL is going to be stretched thin. In other words, prior to the snap, the Miami OL has identified six possible pass rushers, and has worked out their blocking scheme accordingly so that no two OL guys will block the same defender (b/c then that would leave another defender unblocked). But when Hill drops back to spy, and the same for Mohamed, the Miami OL has wasted two blocking assignments on defenders who aren’t pass rushing. This will hopefully confuse the OL long enough for the real four pass rushers to get more pressure.

Cal uses its 3-3 nickel defense almost exclusively when Cal is defending a 2nd and long, 3rd and medium, and 3rd and long. It was actually surprising to see Cal’s 3-4 personnel out on the field for this play considering its 3rd and 5. One tendency I’ve noticed quite a bit, is that when Cal uses its 3-3 defense and is playing man, Syd is usually covering the slot receiver. Typically, I think Cal likes to play zones with their 3-3 nickel.

Thanks a lot. Like you mentioned, it seems surprising not to see the extra DB on the field to cover the 3rd WR. But how does this usually work in terms of matchups? I’m guessing a linebacker against a WR in man coverage is generally disastrous. But since we were playing with 4 underneath zones, does having an LB out there make it less of a problem? What would the advantage of having Hagan out there instead?

by calbear112 on Aug 4, 2009 7:57 PM PDT up reply actions  

Yeah, a linebacker on a WR in man coverage is a disaster. Zone defenses don’t require as much athleticism from your defenders. Man defenses require a lot of athleticism from your defenders. So despite putting a slower linebacker in zone coverage (rather than a defensive back), the defense doesn’t disadvantage itself that much.

This defense is interesting because Cal’s 3-4 personnel defense is out on the field, but Conte is out on the field instead of Hagan. Hagan is the normal second CB in the 3-4 set. I think Hagan might have been injured for a bit during the game and that’s why Conte came in on the 3-4 defense. So if Hagan wasn’t injured, and the Cal defense came out in their 3-3 nickel, instead of the 3-4, then Cal would probably have a better coverage defense on the field (b/c a DB is better in coverage than most linebackers), and have a faster defense, but probably give up on pass rushing threat (since DBs aren’t usually better than LBs at pass rushing).

Thanks

1. This is another fine post, and interesting comments.

2. You are helping to redeem the reputation of the internet. (But you still have a lot of work in front of you.)
