"Pav pick apart Roly's game plans." Hello? Is this Matthew Pavlich we are talking about? I actually listen intently to Pav and I've yet to hear him picking apart the game plan. Execution failures, yes, certainly. I recall, for example, Pav saying "they won't like how easily that ball came out." Is this a repudiation of the game plan? Or, is it a failure of execution? Do you specifically know that the game plan allowed that to happen? Do you know when the players are actually sticking it to the game plan? Personally, I've never seen the game plan detail.
I'm getting tired of saying this, but if you don't have the execution skills your game plan doesn't exist out on the ground. If the opposition players are effectively disrupting your game plan you don't have one either. If the opposition backs are covering and blocking your forwards you are forced to bomb it in and rely on big strong marking forwards, which we unfortunately don't have. Is this a game plan failure?
I see no evidence that our game plan is deficient but player quality and experience is clearly deficient.
