Others have brought up the point of good results earlier in the season. They forget to take into account what I call Phoenix Syndrome: "good overseas players who get worse the longer they are with the club"*. Roly Bonevacia is of course the prime example of this (which reminds me, is he tearing it up at WSW or not? Haven't paid attention). I believe it's a matter of being gradually assimilated into the club culture.
People have a right to disagree with me, but I stand by my belief that there is a culture at the Phoenix of not giving a shark about results and performance, because:
a) as the only Kiwi team, there's a guaranteed audience anyway;
b) as the only Kiwi team, no-one expects us to do better.
c) as Anfony Hudson once said, there's a culture in Kiwi football of thinking that once you're a pro you've "made it" and you don't have anything to prove anymore.
I used to think this was a Wellington thing (i.e. Wellingtonians will defend the utmost levels of shark as long as it comes from Wellington), but I was wrong because the Warriors are succumbing to exactly the same illness. Why are the Breakers, in contrast, doing extremely well? I can't figure that out.
* Iffy and Greenacre being the exceptions to this otherwise solid rule.
Roly Bonevacia was signed as defensive cover behind Albert Riera he was a fringe Eredivisie player and obviously talented but was mainly signed because he was available and had pedigree (which is typical of Ernie).
Ernie converted him to an AM player and his career actually took off. I think it's fair to say he found form at the Phoenix rather than lost it.
There are plenty of exceptions to what you said:
* Krishna
* Riera
* Ifill
* Greenacre
etc
Even Bonevacia performed very well for the nix, add to that Rossi, Paracki, etc.
Plenty of Australians have come here and performed well or better than well:
* Burns
* McKain
* Vukovic
* Vidosich (so far)
etc.
The players that backup what you said were all older and at the end of their careers, so it's more of a fact that the Phoenix were recruiting based on reputation rather than potential rather than recruiting players at their prime and destroying their careers.
