Trap is the most underutilized play in football in my opinion. While I see a fair amount of this play run at the high school level, I very rarely see it at the college and NFL level. Since Jim Harbaugh has come back to Michigan he has implemented the trap play in a number of different ways. Personally I love this play because it allows your running back to get downhill quickly and you get great angles at the point of attack for your offensive lineman. Plus there are so many variations of the play that you can keep the defense off-balance, while keeping the blocking scheme up front simple for your lineman.
The first version of trap is Pro Queen-Z Jet-Tight Trap. Pro Queen is the formation, which means a Pro set with the fullback offset opposite of the tight end. Z Jet indicates the motion from the flanker. Tight Trap is the blocking scheme, which means a trap blocking scheme to the tight end side.
The Jet motion from the Z receiver distorts the run fits of the Michigan State defense. All three linebackers overrun the play, allowing the fullback to hit the A gap untouched, en route to a 28 yard gain. The footwork from the QB is also key. He opens up to the Z receiver like he typically would to give the ball on a jet sweep, influencing the linebackers away from the play. Adding to the deception is the QB spinning into the the give to the fullback, making it difficult for the defense to locate the ball. The defense also gets a split flow read from the tailback running away from the play side with the jet motion.
The next trap variation is run out of a Double Wing I formation. In the previous example the fullback was the ball carrier, this time the give will be to the tailback. By using the tailback as the ball carrier it allows Michigan to modify the blocking scheme slightly. In the first example the Left Tackle had to use a sift technique in order to account for the Will linebacker. Sift means that the left tackle will chip the defensive end and work up to cut off the Will. Because the Will ran himself out of the play in the first example, the Left Tackle simply stayed on his block with the defensive end. On this play the fullback will block out on the defensive end lined up over the left tackle, allowing the left tackle to work directly up to the Will. The rest of the blocking scheme remains consistent.
Here are some additional trap cutups out of various formations and blocking schemes.
Old school gap schemes like Trap are one of the reasons I enjoy studying Jim Harbaugh’s offense. Football doesn’t always have to be complicated. Making slight adjustments to a simple scheme like trap can allow you to run this play in multiple ways and aggressively attack the interior of the defense.
