Wide outs are positions in American football that refer to the wide receivers, who line up on the outermost edges of the offense. Some synonyms for wide outs include flankers, split ends, and wide receivers. Flankers take a similar position to wide receivers, but they line up further back from the line of scrimmage. Split ends line up on the same line as the offensive tackles and are usually the primary receivers on the play. Wide receivers refer to any player who can catch a pass, but their primary position is on the outside. These positions require speed, agility, and accuracy to make the catch and provide a critical element to any successful offensive strategy.
