The timing of this is needs more focus. Was something big about to go down? Griffen to Swans?
Perhaps the AFL have found Sydney haven't been phasing out COLA in their 2014 & beyond contracts.
There has to be more to it for this to happen four days into the trade period, and six days into the FA period.
Can't see it being Griffen - plenty of coverage there. And the AFL see the contracts - so they'd know what the new ones would contain (maybe not Tippetts extra one). Gotta be something in it though.
