Gold Coast sacking McKenna was one of the dumbest moves ever made. If Gaz hadn't done that shoulder they'd of played finals, Bluey would still be coach, Matt Priddis wouldn't be a Brownlow medalist and we probably wouldn't be having this discussion.
Brisbane looks like they've landed the right coach now. Gold Coast might get lucky on their next one too.
The interesting thing about West Coast and Simpson though is that Woosha wasn't sacked, he raised the white flag and basically conceded that turning this core group of players into a Premiership side was beyond his capability as an elite leader and manager of men. Which despite being an absolute inditement on the senior players that has since proven to be entirely justified, meant that the circumstances Adam Simpson found himself in coming into the club were extremely unique. Usually a coach comes in and is starting fresh with a club that has probably just hit rock bottom. He's not just a breath of fresh air his vision and leadership and ability are things the club desperately needs, he's the most important man in the organisation by a long way at that point and that is something coaches thrive on. It wasn't really the case when Simpson took over. The Eagles had missed finals in 2013 but gone deep in 2011/12 and were ready to go straight back into the 8. He wasn't really hired to do anything but tweak an outfit that was up and running.
Woosha pretty much created a spontaneous handover scenario, more like the situation Buckley, Longmire, Goodwin found themselves in except Simpson wasn't on the inside and didn't have the advantage of intimate knowledge of the playing group as at Collingwood, Sydney, Melbourne. Consequently everyone got a clean slate under Simpson and he's wasted 4 years discovering the same things about the same players that Worsfold knew were beyond any coaches ability to change as far back as 2012.
