Cale Hooker will be the easiest to get to Freo, free agent, local boy etc. I think the back channels between Cam Macs manager, GWS and Freo are wide open and as previously stated, GWS will now be desperate to get something for him. I know technically if he finishes with GWS early in his contract he would have to nominate for the draft. But seriously no one other than Freo or WCT have a snowflakes chance of getting him and he has already stated his preference for Freo. Pretty confident a deal will be done there. So the only real horse trading would involve either Hogan or Jeager Omera who have both trotted out the old "Contract talks on hold I just want to concentrate on my footy" line. ( who knows the way Cams drama has played out may have had something to do withy them holding off resigning).
We will also have some heavily payed vets retiring at the end of the season so our salary cap will be in good shape. Anything is possible if the negotiations are handled right.
