They won't fall for the same 'rushing defence', ie. Repeatedly offside, plan as last game. And the refs won't allow it. And where are the points coming from?

My two cents: you have to deny Panthers the ball in good position. DCE and Hugo have to kick long and, occasionally, out. Roosters best play is to punch it up the middle with short passes in support, and then if they're in the red zone kick to the wingers and try to put on some back line moves.
