9. Scrum-half

Scrum halves form the all-important link between the forwards and the backs, and are invariably at the centre of the action. A scrum half is normally relatively small but with a high degree of vision, the ability to react to situations very quickly, and good handling skills.

They are often the first tackler in defence and are behind every scrum, maul or ruck to get the ball out and maintain movement. They put the ball into the scrum and collect it afterwards; they also are allowed to stand further forward than other backs at a line-out to try to catch knock downs from the jumper.

It is also not unusual to have talkative scrum-halves in competitive situations. Though technically illegal, most scrum-halves will subtly alert the referee to fouls and infringements committed by the opposing team.

10. Fly-half

This position is one of the most influential on the pitch. The fly-half makes key tactical decisions during a game — whether to kick for space or tactical advantage, move the ball to his outside backs, return the ball to his forwards to drive on to or run with the ball himself. An ideal fly-half should be a fast and deceptive runner, be able to make decisions quickly, direct the backline on defence and attack, have excellent kicking and handling skills and the ability to cope under pressure. Strong leadership skills are crucial for this position, as well as strong defensive skills.Games are rarely won on tries alone, and a fly-half who is also the goal kicker (which is often the case) can be the most important player in the side.

13. Outside centre & 12. Inside centre Centres need to have a strong all-round game: they need to be able to break through opposition lines and pass the ball accurately. When attack turns into defence they need to be strong in the tackle. Usually the two centres are divided into outside centre and inside centre, though sometimes teams play with left and right centres.The outside is typically the heavier, more powerful of the two centres. They are the “rapiers” that are given the ball, normally via the fly half, or inside centre to make breaks through the opposition backs before offloading to the wingers after drawing the last line of defence. Good size and tackle breaking skills are very important for outside centres to have. They may also need to be very aggressive in defense, espescially when a team is using a rush up style defense.The inside centre tends to be the smaller of the two centres. In defence or attack, the inside centre is always in the thick of the action, drawing the opposition’s defence, making the breaks to make the space for the outside centre and dishing out the tackles in defence along with the forwards. Some of the skills of the fly-half, such as distribution and kicking, can be advantageous to inside centres, as they may be expected to act as fly-halves if the normal fly-half is involved in a ruck or maul.

The wings act as “finishers” on movements by scoring tries. The idea is that space should be created by the forwards and backs inside the wingers so that once they receive the ball, they have a clear run for the try-line. Wings are almost always the quickest members of the team, but also need to be able to side step and otherwise avoid opponents in order to score tries. In modern games, wingers often “come off the wing” to provide extra men in the midfield, in the same vein as a full back, particularly if play has moved away from their wing. Traditionally, wingers are small and fast but since the game became professional (and largely due to Jonah Lomu), wingers are often as big as forwards. Wingers of this variety are often used as extra flankers to gain the “hard yards”.

Wingers often act as additional full backs on opposition kicks. In addition to this responsibility, they must get back from an opposition kick to give the full back options on either side. The modern game means that the back three tend to act as a unit in fielding kicks and counterattacking, rather than all responsibility lying with the full back. Wingers need to have all the skills of a full back, though the emphasis would be on attack rather than defence. As such, many players are as competent on the wing as at full back.

A common tactic is to have the winger receive the ball and then cut towards the centre of the pitch. This changes the direction of play, which may catch the opposition off guard, or may create space for the outside centre to receive a switch pass or “scissors pass”.

A modern use of the wing is as a link player. They retain all the traditional skills of a wing, but are able to combine these with skills more traditionally associated with half backs. As the play goes through multiple phases, the scrum-half or fly-half may be taken out of the play. If this occurs the blind side wing can step in to perform a creative role. Good examples of players filling this role include Breyton Paulse, Shane Williams and more recently Sitiveni Sivivatu.

15. Fullback

The full back stands back to cover defensive options as a ’sweeper’ behind the main line of defence removed from the other backs. As the last line of defence, they require good tackling skills.

They have to catch the high kicks referred to as “up and unders”, “Garryowens” or “bombs”. Having taken a catch, the full back may choose to return the kick, and so good tactical awareness and kicking skills are required. Increasingly often, full backs are used to start counter-attacking moves from depth. Thus, they need to have excellent attacking skills, pace and open field running prowess. In attack, the full back may also run into the back line at pace, providing an extra man, either a decoy runner or an extra man creating an overlap
