I'd say a few backs will go as we have others coming through.
Averillo needs to be retained. Perham/Burns would be another to retain.
Okunbor has earned an extension with his efforts this year.
Flanno should go, as we have BBO still on contract.
Thompson will depend on his only games post injury but would need to be on a heavily reduced contract (but what the NRL apply player value to him).
