The counter sweep is not a common play, but for decades the Nebraska Cornhuskers used it as a primary weapon to power their prolific run game.
The counter sweep is closely related to the counter trey, which became – and remains – a staple in the run game. The blocking schemes look identical at the start of the play, but differ at one key point.
In the counter trey, the pulling guard attempts to kick out the defensive end. The tackle (or sometimes a back) cuts inside of this block to lead the play.
In the counter sweep, the pulling guard “log” blocks the defensive end. This means that – rather than kick the end out – the guard attempts to pin him to the inside. The tackle’s path is deeper in the backfield than on the counter trey, and he goes outside of the guard’s block, looking to lead the play wide and down the field.
The counter trey is a power, off tackle run. The counter action by the backfield seeks to draw the defense in the wrong direction for a split second, which is then exploited by power and numbers at the point of attack.
The counter sweep also attempts to influence the defense to the wrong side of the field, but the play seeks to get the ball carrier as far as possible from the interior of the line.
This resulted in consistent big plays for Nebraska. Of course, Nebraska was also one of the most physical teams in the country, often employing the best offensive lines and the most talented backs. The defense needed to react hard to the play side, and Nebraska exploited that fact by caving in the other side of the line with power, and leading the play with swift, disciplined pulling linemen who were followed by backs who could outrun everyone to the sideline.
While most teams won’t enjoy such advantages, it is surprising that the counter sweep is not employed more often, if nothing more than as a compliment to the counter trey. The two plays go hand in hand. Not surprisingly, Nebraska used a play they called “counter trap” to compliment the counter sweep. Their counter trap featured the guard kicking out the end, and the guard cutting inside of his block – just like the counter trey.
The counter sweep adjustment – at the least – should be installed, to account for a block down step down defensive end. Such an end can be almost impossible to uproot with a kick out block, but is very easy to log block. The tackle and ball carrier should be able to read this block and run to the outside, thus – in effect – executing the famous Nebraska counter sweep.
