Andersen is past it, no question.
But he's also a journeyman, nobody's going to hang his singlet, so whilst I'm sure winning an NBL championship was a highlight, its not THE highlight, nor the culmination of his career.
As the saying goes, you're a long time retired, especially from a sport where decent coaching or media jobs are few and far between.
And the thing with Basketball, is that there is a place for guys who are only good for a few minutes.
Sure, you'd rather see the young turks, but this is now the space that teams like Illawarra need to hunt in. Their days of being able to almost match most of the comp, and being assisted by a salary and points cap, are long gone.
They will continue to lose guys like Kay, and will need to replace him with a combination of unproven youth and cheap experience.
