No, but his time being gone means that he is no longer seeking self-promotion to achieve a coaching appointment for himself.
People who were contemporaries in the 1980-2010s can, and will, judge the accuracy of Stackers' descriptions of the actions he personally witnessed, by directly comparing his "asserted" experiences to their own personally witnessed experiences.
Just saying "Hunt, Derwin, Landon etc., they oversaw an excellent era of international success for Australia" is a even more general assertion, akin to saying Hamilton and Stopford were generals involved in overseeing a victorious WW1 campaign by the allies. Both are correct, but should not actually preclude any examination of less than optimal decisions. I would lay very good odds that no-one outside of a very select few thought that the 2000 boomers were well served by their coaching leadership in Sydney.
Not saying LL and P Hunt were not positive contributors to the outcomes, the fact is that the observations that Stacker makes are actually about all of their contributions, including contributions to the "We own the sport" culture within BA staff at the time.
The only observation he makes about Landon and Hunt is that it was difficult to get appointed if you were not on very good terms with them personally, not that they appointed incompetents.
Nepotism does not inexorably lead to total failure, just unfairness and less success than what could have been possible.
I read it as him saying coach section decisions should result from criteria that are open transparent and made by a well-experienced formal group.
the idea that Penny should have been asking Andrew Gaze "what happened" instead of him asking her is well founded. Choco will get sacked, but the selection committee and process will essentially continue as is, unless people like Stacker pull its failures out into the light.
