“Thunder” is the name we have given to a stunt that will be between our defensive right halfback and right corner man, which will constitute one team, and our defensive left halfback and left corner man which will constitute a second team. Each team will be completely independent of the other team. What the stunt really amounts to is that the halfback and corner man will exchange assignments completely unless the flow goes away from them. For example, let’s say the offense runs an action pass to their right side. With an action pass of this type, our left corner man would ordinarily drop back eight yards deep and cover the short flat area. With “Thunder” called, however, he will turn to his outside and sprint back and cover the deep one-third of the field to his side. The left defensive halfback, who ordinarily would cover the deep area on this particular type pass, will come forward and outside and cover the short area the corner man would ordinarily cover. Not only have we given the quarterback an entirely new picture to look at, but we have strengthened our coverage by having our halfback come forward through the hook zone, going to the flat area. “Thunder” is illustrated in [Figure 81].
I mentioned earlier that one of the advantages of these stunts was that it takes away any point of indecision for our corner men. When we are using our regular coverage and the flow goes away from our corner man, he will sprint to his outside and cover the deep one-third area, but when the flow comes toward him he has to key the offensive end and determine if he is blocking, slamming, going down field to block or to catch a pass. The action our corner man takes will largely depend upon the action the offensive end takes. When we have “Thunder” called, the corner man knows on the snap of the ball, regardless of what kind of play the offense will run, he will sprint back and cover the deep area to his side of the field. ([Figure 81.])
The signal caller in our secondary can call “Thunder” for our right side only, left side only or both sides at the same time. If he calls it for both sides at the same time, then the direction in which the offense operates will determine which side of our defensive secondary will play “Thunder.”

“Robber”
“Robber” is another of our stunts that serves a two-fold purpose of eliminating indecision and is an element of surprise.
Our “Robber” will be someone playing defensive right or left halfback, depending upon our game plans. However, we will never have “Robber” called on both sides at the same time.
For example, let’s say our defensive left halfback will be our “Robber,” as illustrated in [Figure 82]. On the snap of ball, regardless of the flow, our left corner man will sprint back and cover the deep third of the field to his side, our defensive right halfback will cover the deep middle of the field, and our right corner man will cover the deep one-third to his side of the field. On the snap of the ball, our “Robber” can go anywhere he thinks the opponents will run. This is a very good element of surprise because we will get an additional defender at the point of attack and he can be very reckless due to the fact that he does not have any designated responsibility. We expect our “Robber” to try to second-guess the opponent’s quarterback. When a pass play develops, he is in a very good position to break up the short passes.
We do not use this as a steady diet, but we gain considerably by having the “Robber” pursue the ball recklessly.
