Just looking at players that are actually off contract & available, I think that Taylan May is an obvious re-sign for the club.
If Sullivan stays- he's the back-up #7. If the Rabbitohs decide to keep him, the club needs an option at #6/#7 as a back-up. Tom Duffy, Sean O'Sullivan or even Blake Taafe might fit.
I suspect we upgrade Makasini next season. He might start as development & move to Top 30 as the season goes on. So I expect we might look to fill just 29 spots.
That still leaves us short at least 1, maybe 2 outside backs/fullback options. Staines is in-house. As is Mapapalangi & Tu'itupou & both could be upgraded. If the club looks outside, maybe Harley Smith-Shields from the Titans? I quite like the idea of Tyrell Sloan though because he actually adds something we don't have in his pure athletic skills & speed. Doueihi is obviously in-house as well, but I'm concerned about the Isaac Moses thing. Mawene Hiroti is off contract from the Sharks too & if Doueihi moves on, he could be an option.
So with 8 spots available, I think 3 get filled by backs with 1 kept for Makasini to move into.
1. Taylan May
2. Doueihi/Hiroti
3. Staines
4- eventually Makasini
In the forwards, I've suggested Freddie Lussick from the Warriors a few times- he's played #9, #13 & now is playing as a 1st receiving front rower- extremely versatile in a very successful KOE squad.
Mason Teague is buried at Newcastle & is a workhorse #13 that has played well when given the chance. I think he could play a role. Can also fill in at #9 if required.
I expect Tristan Hope probably gets re-signed as well.
Jack Hetherington is off contract. (Insert rolling eyes) However, he is an NRL quality player, great athlete with size, he brings the attitude we lack as a club. He's not a perfect player. I get that. But he adds something we don't have. We are a very passive defensive squad, and not exactly an aggressive attacking squad either. An injection of rage could give the team a boost, particularly when losing the middle.
Another name that I think might be interesting is Mavrik Geyer. Big unit who is young & could add depth & athletic ability to our squad.
I think that adding Mason Teague, Freddie Lussick, Jack Hetherington & re-signing Hope would balance our forwards a little better. If Hope can be a KOE/development addition, then Mavrik Geyer could really fill out the back row options along with Sam Fainu, KPP, Sukkar, Seyfarth.
Again- these are just players that are off contract.
