The Eagles are an example of two things at the moment, the first being that their previous coach was holding them back by being stuck in an inflexible mindset when the football world had moved on and made his way of doing things obsolete. Their current game plan is simple and flexible but is based on decent key marking targets up forward and doesn't over rely on pin-point precision.
The second is that both the Perth sides have an ongoing advantage year after year and they really have to stuff up to win less than 13 or 14 matches each and every season, and this season WCE have not stuffed up. Throw in the lure of local W.A. draftees wanting to return there and that does not do them any harm at all in remaining strong on the field.
We are in a massively different environment with much more local competition to firstly attract and keep players capable of making us successful along with all the other things that are essential, and because of that we have to get things right at a level that is much better than our rivals. We might get things right 95% of the time and in our own little bubble be satisfied with that, but if your competitors get it right 97% of the time then they just increase the gap, that is the story of organisations that don't achieve the top levels of success in highly competitive environments.
We have done ok to get where we are now with the playing list we have and the game plan we use, but right now we are just another middling side that could finish any season from 5th to 12th depending on the fixture and injuries, and it would be an exception to go further unless we can play consistently better football when it really counts.
