It's not just about tackling and Defence in that sense.
The biggest factor has to do with field position.
Penalties for example lose you ground, in this context = bad field position and the penalty, penalty try saying is well known in the game nowadays.
Even at the under 18's game last night both sides conceeded several tries straight after conceeding a penalty.
Also how you get through your sets and completion rate turning the ball over cheaply in your own half = bad field position.
Standard of kicking game, good kick = good field position or a repeat attacking bad kick = bad field position etc.
I don't think our discipline has been too bad this season but our completion rate both in exit sets and attacking sets has been below par and our general kicking game not much better at times.
A key factor will be discipline and that will mean adapting to how the game is officiated on the day and composure who does the basics right on the day.
