Yep I think that's very fair. A clear best 6 spines (side note: that Dolphins spine likely costs them only a bit over $2 million, cumulatively), and then it should be the case that we should be somewhere just after that if the coach knows what he's doing at all.
That's what's crazy about the NRL, it's the most important part of the team and no one seems to be able to get and keep a stable combination together... except the team which finishes in the top three almost every season. With Brown & Moses broken up, Tricky and Nicho are the longest tenured halves combo (since late 2023), next would be Isaiya Katoa and Kodi Nikorima, who play for a club that is only three years old lmao. And that's just halves.
Get a good period of continuity, and that correlates strongly with good regular seasons, and at least a chance at winning something, even for clubs that aren't thought of as being on that 'top' tier, and/or you're doing it without a ridiculous Melbourne-style quartet: Mahoney/Moses/Brown/Gutho; Cook/Reynolds/Walker; B Brailey/Nicho/Kennedy; Granville/Thurston/Morgan/Coote.
And in a comp full of clubs which can not get any spine continuity going at all, we have probably been the absolute worst for it.
