There's plenty of reasons why he might not have re-signed at this stage. Being out of contract, he and his manager are clearly testing the market to see what he is worth, before he accepts Brisbane's reported contract offer of $400,000 over three years. If another club offers him more, then he may well be advised to accept that offer. If Brisbane up their offer to match or exceed what a Melbourne based and / or Adelaide based club might offer, then he may well accept that.
My point was that your source or "mail" is no better than mine. Why are you right?
I personally doubt whether 'liking" Brisbane as a place to live, figures that strongly at all in Aish's deliberations about his next 2-3 year AFL contract. That's my opinion only, based as it is on my "mail" that he likes the club and his team-mates.
And even if it did, very few of us would be any the wiser. Even your source. It's speculation at best and not necessarily the truth.
"Mail"? I haven't seen anything about whether Aish himself is interested in a particular Melbourne club, beyond media speculation.
There may well be a number of Melbourne based clubs interested in a No. 7 DP taken in 2013, who's played 32 senior games in two years, finished fourth in last years rising star award and who is currently out of contract, but that's a different thing.
Let's see if Adelaide now makes Aish an offer that matches or exceeds $1.2 million over three years, now that it appears Dangerfield has supposedly requested a trade to Victoria.
