A slant route is a pattern run by a receiver in American football, where the receiver runs up the field at approximately a 45-degree angle, heading to the gap between the linebackers and the linemen. Usually, the pass is used when the corner or nickelback are playing further away from the receiver, so a quick pass is able to be completed before the defender has time to try to break up the pass. The pass is used frequently in the West Coast system, where quick, accurate throwing is key. This route is most commonly used to exploit the cover 2 defense. Usually throwing in the seam between the safety and the cornerback is the key to getting a completion using this route.
