Samuel David Koch is an American former professional football player who spent his entire 16-year career as a punter for the Baltimore Ravens of the National Football League (NFL). He played college football for the Nebraska Cornhuskers and was selected by the Ravens in the sixth round of the 2006 NFL draft. He is known for developing many punting variations, revolutionizing his position in the process.

A punter (P) in gridiron football is a special teams player who receives the snapped ball directly from the line of scrimmage and then punts (kicks) the football to the opposing team so as to limit any field position advantage. This generally happens on a fourth down in American football and a third down in Canadian football. Punters may also occasionally take part in fake punts in those same situations, when they throw or run the football instead of punting.
