Curl (route)

A curl route, also called a button hook, is a pattern run by a receiver in American football, where the receiver appears to be running a fly pattern but after a set amount of steps or yards will quickly stop and turn around, looking for a pass. This generally works best when the defending corner or safety commits himself to guarding the fly and is unable to stop quickly enough to defend the pass.

The curl is a pattern used frequently by the West Coast offensive scheme, where quick and accurate passes are favored.

Curl (football)

Curl or bend in association football is spin on the ball which will make it change direction, called a 'screw shot' in the 19th century. When kicking the ball, the inside of the foot is often used to curl the ball, but this can also be done by using the outside of the foot. Similar to curl, the ball can also swerve in the air, without the spin on the ball which makes the ball curl.

Curling or bending the ball is especially evident from free kicks, shots from outside the penalty area and crosses. Differences between balls can also affect the amount of swerve and curl: traditional leather footballs were too heavy to curl without great effort, whereas the lighter modern footballs curl with a lower effort threshold. As a general rule, the lighter and smoother the ball the more deviation there is.

Nomenclature

There is a degree of confusion surrounding the correct naming of different aspects of curl. The technique of putting curl on a ball is known as chanfle to some, from Spanish, and also as the Trivela. The deviation from the straight path in the air is the actual curl, or swerve; however, the spin on the ball that causes this is also known as the curl. Shots that curl or swerve are known as curlers, swingers, or ones that bend, also in extreme cases, banana shots. However, it is extremely rare, these days, to hear any shot described as a "banana shot".
