I think the club needs to circle the wagons and appoint a single spokesman (not Gareth but good luck shutting him up) and tell everyone else to zip it (including Brockie).
Let Herbert play whatever way he wants for the rest of the season - the seasons rooted now anyway and if it wasn't already clear before it is certainly clear now that a substantial portion of our squad are not up to playing a better level of football or are past it.
I'm sure the owners will learn from the experience may be taking the rest of the season on the chin but I expect a serious squad cull next off season.
How Herbert fares after the season ends will depend on his role in the debacle e.g. when was the decision made to change playing style relative to the re-signing and recruitment decisions last off season and what assurances did Herbert give on the ability of Smith, Sanchez, Muscat etc to play the new style.
I don't expect him to be sacked but I do expect him to be on a lot tighter leash than he has been in the past, particularly with respect to recruitment - given his recruitment track record that can only be a good thing.
I also expect the owners to progress, more aggressively, a succession plan for Herbert.
