1.0 IntroductionWith the improved defensive abilities of teams in the last decade, linebreaksare being minimised. The actions in the lead up to a linebreak occur in adynamic environment. Due to defensive players moving and reacting atdifferent speeds and angles, attacking players need to be aware of potential
threats and react accordingly.
This paper will analyse the creation of linebreaks in Rugby Union. Factorsthat will be included:
Definition of a linebreak
How the line is broken decoy runner, broken tackle, etc
Who breaks the line:o Individual playing positionso Groupings tight 5/mid 5/back 5
Where the line is broken:o Individual playing positionso Longitudinal field position:
Green zone (22m line to attacking tryline) Amber zone (22m to 22m) Red zone (22m to defending tryline)
o Latitudinal field position: Narrow Mid Wide
Passage of play the linebreak occurs in:o restarto 1- ? phaseo groupings:
restart 1 - 3 phases 4 6 phases 7 9 phases 10 + phases
Time in the game the linebreak occurs
Research Groups:The following teams in the Super 14 were tracked (Refer to Appendix 3):
Queensland Reds
NSW Waratahs
ACT Brumbies
Western Force
Outcome:Based on the findings in the research, coaching implications will besummarised in terms of the skills required by players to provide linebreakingopportunities.

2.0 Linebreak by DefinitionLinebreaks for the point of this research paper are defined as those ballcarriers that cross the gain line (imaginary line that runs from sideline tosideline through the middle of the ball winning contest) and break through thedefensive line either between defenders(see Linebreak 1 diagram) or on the
outside of defenders (see Linebreak 2 diagram).
Metres gained from short kicks are not included as this paper is isolatingindividual skills the ball carrier and those supporting players must display inorder to create a linebreak.

3.0 Definition of Linebreak ElementsFrom the 50 Australian based Super 14 games tracked in 2006, 201linebreaks were recorded which equates to 4.02 linebreaks/team/game.
Table 1 Definition of Linebreak (LB) Elementsexplains each element and
the rationale behind using it.
Table 1 Definition of Linebreak ElementsElement Explanation
LB Playing Group Attacking players were divided into 3 groups:1. Tight 5 LHP/Hooker/THP/Left Lock/Right

5.0 Summary of Coaching RecommendationsThis analysis shows the various skills needed to create linebreaks. Thechallenge for coaches is to understand the skills required to create a linebreakthrough preserving or creating space in the defensive line. The impact ofimproved defensive players and patterns means it is rare for one player (eg.
Jonah Lomu) to continually dominate tackle situations by simply running at themid point of a defender.
Coaches must then transfer this knowledge and range of skills into simplisticand progressive activities that provide players with an environment where theytrial and learn various skills in game situations. Feedback needs to bespecific with open ended questions mixed in to gauge the understanding ofwhy players are choosing various options.
The critical aspect in coaching players to create and preserve space is theirability through their running angle and footspeed to manipulate the shoulderposition of selected defenders. Space simply will not open up in higher level
games. It needs to be created through the attack being able to disrupt orbend the defensive line out shape.
The skills identified in this research paper have been arranged in Appendix 1 Skill Matrix for Linebreaking. A prescribed order of events has beenincluded to generate thought on how to logically coach players in the art oflinebreaking. Other skills or a different order may be best, the bottom line isthat players require coaches who understand how to create or preserve spaceand ultimately coach it in an easy to understand manner.
In conclusion, various skills in linebreaking have been identified withconsistent themes that have implications on how to coach attack. Whenanalysing the results of the games tracked, linebreaks are more likely to occurin the following environments:
3 phases or less. Of these, 55% of linebreaks occurred in general play.Therefore players must have the ability to play in an unstructuredenvironment and be able to scan and execute a range of actions to suitthe attacking environment. In addition, first receivers need to correlatedepth/flatness in relation to the speed of recycled possession. Eg.Quick ball = flatter alignment as defences are retreating and have lesstime to react (if this is a style of play you coach)
Back 5 group is more likely to break the line, in particular the fullbacksand wingers which equates to width in attack. 72% of linebreaks
occurred 10 m and beyond with 37% of linebreaks occurring 20 m +.As a result the ability to catch and pass is again critical in shifting theball to space
Linebreaks occur more between the two 22 m lines. Coupled withlinebreaks only averaging 20.96 m with 76% of linebreaks requiring asecondary action before the 30 m mark, support players are critical incontinuing the attacking movement. In addition, teams probably arenot prepared to risk in the red zone. Tim Sheens (West Tigers Coach)articulated that simply because it is the red zone, players already have

AAnnaallyyssiissooffLLiinneebbrreeaakkiinngg
18 JJaassoonnGGiillmmoorree
a preconceived idea about exiting the area. With only 3% of linebreaksoccurring in the red zone, is there an opportunity for confident andskilled players to take advantage of defences who are more than likelyprepared for a kick to touch with wingers generally back already?
In summary, the ability to create a linebreak requires a progression of
dynamic actions. With a number of defenders, attackers and the footballconstantly moving, attackers need to be focussed and understand which skillsto implement depending on the environment confronting them. This hasimplications for coaches to train and provide players with opportunitiesthrough training to experience linebreaking situations. These implicationshave been identified in this paper. How they are coached is up to thecoaching style and philosophy of individual coaches.
