Actually FWIW, I think we might have a similar setup re cumming and Hamill. If we don't get cumming Hamill will be retained.I reckon the plan is if luko doesn't join us, we offer himmelberg a decent contract, if he elects to go then we can't stop him and we retain Burgess as our depth tall forward. If luko joins we don't offer contract to Berg and cut and payout Burgess, if luko doesn't join, Berg accepts contract we cut Burgess. Something along those lines.
These suggest that the club doesn't consider Luko or Cumming to be done deals. Far from it.
