Well IMO we can definatly rule out guys like: Hayne, Hindy, Cayless, Inu, Reddy, Fui, Mannah, Poore, Shakelton, KK, Mortimer, Mateo for reasons like it would be plain stupid to release any of the above.
That would leave guys like Hauraki, Burt, Grothe, Oake(rumoured already released), Robenson and Mitchell.
Now I cant see guys like Mitchell, Burt, Robenson being on big money so Grothe might be on the outer due to his salary but he has been playing well and it isnt like we have an abundance of backs to release him.
Maybe the release of Hauraki and Oake plus the signning of someone we all wont be happy about? Maybe Filiga is not going to be offered a contract? who cares just wait and find out
