I think you are being Bias here in thinking the eagles had that callDepends how likely the club sees Warner, other potential targets, or the viability of guys like Hutchinson or Chesser to play in the middle
Saints may have promised him guaranteed midfield time, we may not have been keen to do that.
Or maybe McQualter just wasnt keen on a guy with Carrolls attributes
I personally think SoS convinced him he has a better future at St Kilda or gave him a longer contract
3 years $500k would have got him to the eagles and the club should have made sure he was an eagle
