Is there a Rendell player here (or at Collingwood)?
That said, its' certainly possible. 4 different coaches, 4 very different styles of players needed (5 if you want to include that Pyke ended up being an absolute mess of a coach after 2017 who spoke of wanting to play a fast paced game, and ended up going slower and slower). We certainly haven't had an identity, and really, we probably haven't ever had a identity of what player you'd call an Adelaide one (outside of "he's South Australian" for the first 5 years).
The biggest issue Hamish faced though is that he was the unfortunate person to be the head recruiter when off-field we just fell apart and started to bleed one capable person after another, and kept digging into the bargain bin. On top of having utter dross at the top of the food chain (Burton, Pyke, Fagan, Roo, Campo etc). I don't think it's too surprising that his record goes bad around 2016 once you had draft groups spending a lot of time in that period of just garbage off field management.
Edit: I rewrote it, as I misunderstood the question initially.
I don’t buy any of that. Hamish just doesn’t have a good record. And it’s not good as soon as he took over in 2012
