      Forming a tackle triangle and getting onside in defence

      Lesson details

      Learning outcome

      I can form a tackle triangle at the breakdown and get onside in defence.

      Key learning points

      1. Move: stepping quickly into a triangle with 2 other teammates after a tag/touch helps to slow down the attack.
      2. Move: moving quickly onside, behind the tackle triangle, stops gaps forming in the defensive line.
      3. Think: 2 defenders must place a hand on the tagger to set the offside line from the back foot of the triangle.
      4. Feel: feeling organised in defence builds confidence to press and stop forward momentum.
      5. Connect: communicating clearly in the tackle triangle lets the tagger know you are there to support them.

      Keywords

      • Offside - if a player is in front of the last point of contact (the back foot of the tackle triangle)

      • Tackle triangle - a defensive shape formed around the ball carrier after they have been tagged by 3 defenders

      • Phase - a continuous sequence of play that starts after a player is tagged or touched, and continues until the ball is passed, dropped or the play is stopped (e.g. tagged)

      Common misconception

      Pupils think that just the tagger remains at the breakdown in T1 rugby.

      After a tag/touch, 2 other defenders need to join the the tager to form a triangle at every breakdown.

      Teacher tip

      If pupils are already fairly expeirenced with rugby, you may wish to incorporate some contact into the game to make a simplied version of full contact rugby.
