Again, easy to say from a couch but for this match, in attack i would be giving them very simple instructions. If the player next to you has the ball, you should be up there with them.
Fullback: Run through and give the forwards a support option that isnt flat footed. Even if you dont get the ball the first 15 times you run through continue to do it.
Hooker: for forward hit ups, skip out and engage the markers so that they dont pick our forwards off. For the backline straight pass out to the half. Without delay.
Middle forwards: get deep and catch the ball at minimum 50-60% sprinting speed. Find your front if the ball is wrapped or look for a safe offload if arm is free.
2nd rowers: get deep and run a slight angled run between the centre and half (or half's inside shoulder if it is a pre-determined second man play). Run through that gap when ever the ball gets wide whether you get it or not.
Halves: get deep, kick the forwards out of the backline (cant stand this middle forward passing to a half to start a backline, they are too slow and fool noone). If it is a longer backline, the halves should link. The half takes the ball to the line at speed, aiming to get on the outside of the opposing 2nd rower and engage the opposition half. Vary response to this shape by using eyes up footy and either dummying and running, hitting the second rower, hitting the fullback sweeping, going directly to the centre or putting a kick behind the line.
Centres and wingers: position yourself to get the ball on the outside of you opposing player. Chase kicks, call for kicks behind the line when the defence is using up and in or aggressive line speed out wide.
If we can manage these basics we can try to attempt more challenging shapes.
