You don't want to hang on to a socceroo defender? Surely in an Australian league,that suggests you cant do much better than him.
Pav has shown enough to earn a new contract if we have space in the squad for him (since he will no longer be a youth player).
Hearfield is quite a useful utility,played well last season,and is getting better this season.
None of the above (North, Pav or Hearfield) are in my 6.
"I'm not suggesting we get rid of the rest but there are at least 6 I'd personally be relaxed about moving on".
