Here's the thing. We don't have a backup halfback contracted for next season if either of Luai or Latu go down. Yes we have Mason but he's a running 5/8 and needs time.
Sullivan has proven to be a very good bench utility for the Rabbitohs who can slot in at dummyhalf or in the halves.
Unless we secure a Jock Madden or Brad Schneider for $200k to be our NSW Cup halfback & backup halfback, it may be a better play for us to have Bud return if Souths are the only suitor chipping in $150-$200k. That means we'd still have to pay $350-$400k for him to play elsewhere.
I'd be talking to his manager Tartak to throw out an olive branch and discuss the opportunity for Bud to be our #14 hooker, half and also add ball-playing lock to his role in short bursts so we can maximise his value & impact.
I've seen a greater steel in his defensive resolve this season at Souths even at a lighter weight so this could potentially work even at 'overs' if a) he buys in and, b) Benji buys in.
