BPurple, the only trade Melbourne would even consider for Hogan is Fyfe. Nothing, but nothing, else would be acceptable...until he is out of contract.
Demo1, Brisbane have the opportunity to be really, really cruel to their Queensland cousins over Dixon.
Their offer, if it is true, will eliminate any other suitors for Dixon's services.
Dixon is not a free agent (no compo pick for GC) but he will be an uncontracted player. As such he can nominate for the Pre-Season Draft and Brisbane can pick him up for free (using their last, unused pick from the National Draft).
Relations will get decidedly frosty in SE Queensland if that happens.
