Effective defense can only be achieved when players work together to deny time and space to the opposition ball carrier and support runners. At both set piece and breakdown situations. The objectives are the same to minimize the options available to the opposing ball carrier and to regain possession in order to achieve this Defenders should work as a unit align themselves so that they are able to tackle on either shoulder and have confidence in their Inside Man communication and organization of vital factors as is an appreciation of the offside law and the responsibility of every player to make their tackles. In this example, we're in England are defending an Australian scrummage. You can see how the England Defenders working as a unit put pressure on the Australian banks creating a tackle line. Some meters behind the Australian gain line at the breakdown England reorganized quickly. So that as a unit man for man, they cover the opposition overall. There are two players staying deep and a sweeper working behind the defensive line. Here you can see that England. Once again have two players defending deep and a sweeper. Even though the Australians win quick ball England pressure forces their scrum-half to run laterally behind the gain line and the England players are aligned and ready for the Australian change of direction of the resulting breakdown Australia recycle the ball and attack the other way. You can see that the Deep Defenders are moving Crossfield to cover the possibility of a kick. You can also see that England have maintained their defensive line and will pressurize the Australians time and space preventing them from crossing the gain line. From the next breakdown notice how the Tattler rolls away and the Defenders remain on side Australia wind quick ball and continue to attack in the same direction. The central deep Defender stays deep and covers across the other comes into the defensive line, which cuts down the Australian time and space forcing the turnover. Here you can see how England's defense develops from an Australian line out as the ball is thrown in the England backs are in line the regulation 10 meters behind the line of the point of touch two Defenders remain deep to cover for a kick. The lineout ball is used to attack the Midfield and quickly recycled. The attack then continues in the same direction with the England defense aligned to cover the inside pass used by Australia. As the tackle is made notice that England still have to deep Defenders covering a kick and as Australia recycled the ball in the same direction the England pressure on their time and space forces are knock on. From this scrummage the Australian back row move leads to a rock from which Australia recycle the ball the England defense reorganizes quickly and crucially all the Defenders are careful to remain on site as soon as Australia move the ball, the objective of the England players is to minimize their options by cutting down time and space in order to do this the England offenders work as a unit arriving at speed keeping their alignment and have confidence in their Inside Man to make the tackle notice how the outside Defender wastes no time in getting back to contest for the ball from an on-site position. And on his feet Australia are pressurized into conceding a penalty when a defense loses its alignment it can present an opportunity to the attacking team. In this example notice how one of the South African Defenders steps up and in and the resulting dogleg in their defensive alignment creates an opening which gives England's Charlie Hodgson and opportunity to attack and score. key factors are communication organization players knowledge of the offside laws the responsibility of every player to make their tackles. Coaching points are ensure that all players understand how the team is defending all players should appreciate the importance of calling who is marking. Whom Who players need to be and remain on side? If the defense is using a one-on-one marking system players need to know where they should be standing relative to their opposite numbers players should understand how to defend into out-and-out to in. Let's take a look at these two types of Defense. In this 20 meter by 20 meter grid you can see that the red Defenders move from the inside out. Defenders line up inside their opposite numbers and as the ball is moved the Defenders push the attackers from the inside to the outside. Working within a grid 3 Defenders against four attackers will still be able to stop the attack notice how the middle defend that goes up on the inside of his opposite number the outside Defender indicates and calls for the middle Defender to move across he does. So but only when his opposite number has passed the ball this releases the outside Defender to pressure the fourth attacker when that attacker is forced to move the ball back inside the middle. Defender is ready to make the tackle. For announced to in system Defenders line up outside their opposite numbers and as the ball is moved the Defenders push the attackers from the outside to the inside working within a grid and attack can be stopped very quickly. Each Defender takes responsibility for an attacker and runs straight before angling. They're running line in to minimize the opponent's time and space when viewed from directly behind the defender. The angle of the Defenders running line can be clearly seen out to in so too can the effect this has in closing down the attackers options.
