Defensive Strategy Diagram – 46 Defence

"In the sport of association football, each of the eleven players on a team is assigned to a particular position on the field of play. A team is made up of one goalkeeper and ten outfield players who fill various defensive, midfield and attacking positions depending on the formation deployed. These positions describe both the player's main role and their area of operation on the pitch. ...
Goalkeeper is the most defensive position in football. The goalkeeper's main job is to stop the other team from scoring by catching, palming or punching the ball from shots, headers and crosses. ...
Defenders play behind the midfielders and their primary responsibility is to provide support to the team and to prevent the opposition from scoring a goal. They usually remain in the half of the field that contains the goal they are defending. Taller defenders will move forward to the opposing team's penalty box when their team takes corner kicks or free kicks, where scoring with one's head is a possibility. ...
Midfielders (originally called half-backs) are players whose position of play is midway between the attacking forwards and the defenders. Their main duties are to maintain possession of the ball, taking the ball from defenders and feeding it to the strikers, as well as dispossessing opposing players. ...
Forwards (or strikers) are the players who are positioned nearest to the opposing team's goal. The primary responsibility of forwards is to score goals and to create scoring chances for other players." [Association football positions. Wikipedia]

"In American football, the pro set or split backs formation is a formation that was commonly used as a "base" set by professional and amateur teams. The "pro set" formation featured a backfield that deployed two running backs aligned side-by-side instead of one in front of the other as in traditional I-formation sets. It was an outgrowth of the original, three running back T-formation, with the third back (one of the halfbacks) in the T becoming a permanent flanker, now referred to as a wide receiver. ...
A common variant of this formation removes the tight end and replaces it with a third receiver in the "slot" position. The formation is utilized to remove a defensive player from the tackle box to give the offense a 7-on-6 matchup.
There are three formations in the pro set of forms: Pro, Ace, and Tree." [Pro set. Wikipedia]
