Our halves are in a good position with Hunt, Sullivan, Clune and Amone. No need to look elsewhere and waste money as Sullivan and Amone will need upgrades once they hit the NRL with a bang hence why I would offer Sullivan a 5 year deal on 500k a year to lock him in. Put a clause that If he makes reps (NSW or Aust) he gets an auto upgrade to 650k. Clubs will be sniffing around hence why I would do this now.
Norman may be just ok for 1 more year or a year by year basis as back up (like a Benji role at Souths) on reduced contract.
Hunt the same as Norman when his contact is up and work on Amone and Sullivan halves setup for the future of Saints. If Hunt / Norman go, Clune is back up to all 4 as I see some value but not full-timer.
As for forwards, hopefully next week Saints and the JDB saga will be over and they can decide what to do.
