My point is not to deny Bennett the kudos he richly deserves but to give an opinion that those days, those coaching methods are over. I don't think those "Bennett" basics have relevance any more, not least of which his " wait for them" style of defence, one-out running up the middle, and his reliance, similar to Seibold's perversely, too much on quality individuals "playing what's in front of them" as opposed to drilled structures. Contrast his methods to those of Bellamy - they just work whereas Bennett's Souths are nowhere near that level.
I don't agree this mess is all on Seibold. He played his part but he is not the problem, he is a part of a much bigger one. I think it's important not to lose sight of that otherwise, the board has an excuse to avoid and evade accountability, and also sets up a new coach to fail to meet our high expectations.
As for Nathan Brown, I will reserve judgement on him until he has a year with his new club.
