Inside the Playbook: Purdue's Weakside Flood and the QB Keep Concept

Purdue is a "concept" group; I mean they had a few dozen concepts (more or less) and built a lot of them. In many ways it is a very effective way of building high speed, high speed destruction. They combine individual concepts and your playbook can grow to hundreds, but your players only need to learn a few dozen concepts (including racing concepts). You make the game easier for everyone: OL OL and QB, and above all your QB and WR. Since what you learn is limited, you can study it in more detail, which means you'll understand the details and adjustments that can be made immediately. QB and WR get a lot of repetition by just playing a few games, and they help each other read and edit in games.

One concept I would like to explore in detail is weak flooding.

Weak side flood

According to him, one of the concepts used by Erdu is weak flooding (often called the concept of QB Naked or QB Keep). This concept provides high/low readings on the CB and loop resistance; This is also known as reading triangle. Some defenders covered the space they used when running into weak formations because they needed a strong defense to withstand the dangers of flying. In addition, this concept is often associated with fake action games; The highway from the opposite side of the field serves as a downhill TE or WR, allowing the game to adapt to this pattern.

Erdu likes to sell purchased corners. It runs at a distance of 3-5 meters from the hash, then runs vertically before returning to the corner at 10 meters. It does a few things on offense. First, it helps to sell the PA a bit (cut edges or makes it more secure), but draws attention to safety and helps define CB coverage. By attracting the attention of the gender, you will prevent him from cheating so much. They also build a uniform wall so that it passes under the receiver flat, eliminating input-to-output coverage. As for the meaning of CB coverage, when the receiver comes, the CB follows or is released. When he called, the reading was clear to QB. When released, the cube can determine whether the CB moves backwards (opens the middle and returns to the inner third) or bends (keeps feet flat forward). This will help QB as we will see in the process section.

flat cross

TE always wanted to release it unless there was a 7-tech shield. He can only work under the ^2nd line of defense, but ends up having to work 5-6 meters deeper when hitting the opponent's OT. At that point, he started looking for QB for the ball. Looking back, he continued on his way to the tangent line. When the throw window opens, QB throws the TE open (either to stop it or change it to its current position).

Middle Cross

Unless there is a TE and there are no 7 technical defenders, the receiver will always be released. On the other hand, it needs to be behind a Level 2 ^defender and work up to 10-16 meters (as a first and level hook/curve protection). Usually, the first rod is worked at an angle of 45 degrees for the first 5-7 meters. We will return to this "remote hash" concept at the end of the article.

Growth

The first key to a move is a defender outside the receiver, usually CB. When the CB sinks (short or deep with it) with WR, the key to moving is the hook/curve shield, which is moderate risk on plate and hash on hash.

CB is falling, stay inside

CB falls, Will change

My note says hook/curly guard, which could be the LB's weak side or deep security; Change and QB should identify the touch of the second movement. A mistake that can easily get your claim rejected is failing.

CB, FS sink is cooling

On the other hand, if the CB stays flat and stays flat, the lock on the next QB move works safely, and the right corner and center cross serve as internal/external threats.

CB set, FS cut the cross

CB saved, FS succeeded

QB are very comfortable with these criteria and it is important to get the ball out of their hands. In this concept, being present at the time of tossing is the key to a coin's success. The pitch is compressed if you flood one side of the court and usually drive in that direction. This helps with reading QB, but also allows him to play fewer defenses he's allowed to respond. After the move is made, the ball must be out of bounds and the QB must read the 2nd move touch ^and move quickly to the 2nd move touch.

Example

Example 1

Erdu is on the pitch in a triple formation (TE and two WR on one side; WMU at 4-3 with SAM loose and showing a 2-way defence.

In a moment you'll notice that QB gives the wrong outplay when OL starts to slip. The X-WR already faces deep security at home and the Y-TE faces a cross with long range LB. You can also see that the Z-WR begins the transition by working straight inward.

QB hits the ball and starts a naked roll to the right. You can see in the next photo that the CB is driving backwards, staring at the X-WR. Immediately, that is the key to turning your gaze inward. He threw the pitch straight away without anyone noticing.

The safe and sinking CBB was dragged down the banana path, the center cross wasn't even ready to be made, and as soon as the house windows were opened, the ball was out of QB's hands.

And it leads to TD

Example 2

Same formation, Erdu just reversed as it is now in the left hash. WMU showed a slightly different formation, SS folded under 4-3 above the gap.

As the receiver begins their journey, the mesh point sees the defense. WORK up to ² levels and hit MIKE halfway before it's released.

CB follows X-WR clearly again but with the help of security above and QB sees CB fall, he runs the 6 step half pack, looks in and waits to see the second lock and waits to open the window.

The window opens and TD.

Example 3

Now let's look at the attacker, not just the apartment. Erdu had wings on the TE and the pitch in an I formation and the edge split at the boundary (in WCO parlance: emphasis on the left green), but we played the same game.

Here's a slightly different protection plan.

The X-WR started the banana path from the inside with the rod towards the hood, the Y-TE started a flat cross after the stroke sold out and the kite started going deeper into the center cross.

CB followed the X-WR, but when QB turned his gaze inward, he saw a weak sidecar swinging sideways. Growth should lead him to the middle cross.

QB won't find it or won't find it too late (which puts it in FS to bypass the route). If he had finished reading on time, he would have hit the cross in the middle of a fine win, but he couldn't because of his delay. He finished the cover one-on-one, it wasn't a bad call, and WR created a spectacular scene for Teddy.

Same concept, different look

This is where the concept of Keep comes in handy. Since we generally have receivers in the same three places, we follow the same basic concept because outside of games and QB do the exact same reads, but different staff may do it differently. .

Example 1

Here, the tympanic membrane features near-border stacks, a wing on the pitch, and a wide hash-cracked X-WR. A lone breeder stands behind QB in the middle.

QB fades a section on the right and OL slips on the left. The underwing prevents the ED from staying there. Downfield X-WR initiates turn-off from the inner beam. To return to the stack, WR dominance is a deep direction for safety when a missing receiver makes a middle crossover (a missing WR doesn't start slightly outside the main receiver, the stack often connects an external CBN to that receiver and the stack acts as a collision due to the two switch positions receiver with axis). Finally, note that when the breeder tries to get into the apartment quickly, only six fakes will work.

That's right - it's like a TE running on a flat track. Everything else is the same. The QB reading is the same. That means it's all the same for attack, but it's a new perspective on defense. Low flank in ED is enough to sell defense. When QB followed X-WR to cover, he could see that the eye immediately moved in and PA Arby had enough time to keep OLB from sliding onto the plate. When Arby returned to Los Angeles, he was kicked out.

That's what it looks like.

And it turned into a big win.

Example 2

Purdue returns in a single back formation, with wings on the tee and border and stacks on the floor near base. SIU has three depths on the back of the top layer of support.

No play action takes place here and both teas remain closed. Breeders work the pavement, outside WRs walk around street corners, and lesser receivers run to hash the field before threatening vertically and sitting on the hash.

It can be seen in the previous photo that the CB is flat and straight when clutching the Z-WR. QB immediately noticed because the scope of support was not well defined. But that's a big part of the game's design: pushing the staple cover; The external receiver enters the internal receiver and terminates it, but it is the external receiver that runs the corner and pause paths that enter the pause path. In other words, a roadblock was created to attack from the front yard. When the X-WR arrives at break time, the QB is ready to jump in and finish reading. The CB sits firmly on the bottom line and the fuse is fixed in it, making it easier to identify the diagonal.

This is what it looks like.

And to sit under the CB is a very simple TD throw.

Example 3

Oh, but our favorite West Coast Destruction book is Spider 2 Y Banana. And you can manage this game in many ways.

How does Arbi do a cross as a flat threat (by cutting FB DE), the TE of the match as a diagonal, and the opponent's TE as the center cross.

How about an unbalanced line, FB as a flat threat, TE as a diagonal line, and the back wing as a center cross.

What about the yogi concept ? Yes, very similar.

Short

Closing

The thing is, you can see a lot of defense and make things easier for the QB and receiver. That means it was a design failure. Basically, the concept is as follows: the receiver runs through the player into a corner street (many coaches practice throwing it like an "alarm", watch before you continue); The receiver goes out of shape - the edge of the plane, far plane or back and moves a short distance to the side; The third receiver threatened the middle of the distance behind the flat. When combined, these three paths make the triangle QB make the same sign each time.
