An element of an offensive play that requires a player to run a specific route on the field. Pass patterns are designed to create open receivers and increase the chance of a pass completion. On a passing play, several different pass patterns will be run by the various eligible receivers. Common pass patterns include the slant, in, out, post, and corner. The quarterback will expect a player to run a certain pass pattern based on the play that was called in the huddle.
Also referred to as a "Pass Route".
Pass patterns are the primary strategy used in offensive passing plays. Coaches will design plays that use these patterns to get open receivers, and allow the quarterback to deliver easy passes to them. Often, patterns will be called based on the defense's strategy. For example, if the defense is playing off of the receivers to take away the long throw, the coach may call a quick slant to take advantage. Certain patterns are called to use the field of play; an out might be called in order to complete a pass along the sideline to get out of bounds quickly and stop the clock. Other plays will use multiple patterns to confuse the defense and exploit it by forcing defense players to choose between guarding two or more receivers.
