On a free perhaps and up until March I would have agreed (especially after O'Hallorhan) but Hussey has been a breath of fresh air. If he continues to develop he can be every bit as good and better. Hussey is excellent going forward and has some pace and strength. Fox is better at dead balls but we have Clingan now. Don't get me wrong I loved Fox and still rate him highly but with Hussey more than adequete then the budget can be better spent then on such a small difference at left back.
