I've just gone and listened to Piney's chat with him, and I wanted to listen to the whole thing rather than get bits and pieces and soundbites that may not have given the full context.
As crestfallen as he sounded in that interview (and don't tell me otherwise that he wasn't down about it) it's a great lesson for him, as it will be for the Nix & Gilly down the line. Football is an ever changing, ever evolving game. It's as quick and up in the air on the field as it is on it. The Nix took a swing for the $$$ tree on his youth, talent, ever presence in the starting XI, his contributions on the park, and ultimately his U23 PotY status to drive home this $xxx,xxx value buyout figure, whereas young Callan admittedly had feelers out abroad via his agent for likely the vast majority of these negotiations, and all the while a contract has been sitting on the counter at home awaiting his signature. Gilly and them would have known what is was, so I don't know whether they can catch any of the "blame" at all on the matter because ultimately only time is going to tell in this instance. He'll 100% find another club no doubt, but I suspect it'll be closer to (former) home than expected, at least initially anyway.
Ultimately, it's a situation where no one wins. We lose a valued member of our side who has a whole lot of potential upswing, and now Callan faces the prospect of Unattached FC, and the whole merry-go-round of issues that come with that hanging over his head.
Best of luck to him though. I'm sure he'll land on his feet somewhere, and hopefully before too long as well. I will secretly be well pissed though if he lands at another A-League club next season and then earns a fee for a move further North.
