There are a few options on who will go first this year, for me:
Arthur - Apart from the 2022 grand final he hasn't really ever lead the Eels anywhere great. Sure, they've made finals but there'd be coaches out there that do much better I think.
Ciraldo - Lots of investment, lot of star players, it is easily a top 8 side but isn't playing like one yet, if he doesn't come close to the 8 this year you'd have to think he'd be done.
Demetriou - Has been living off the great first year he had in 2022 where Souffs made the preliminary final. Anything short of a strong position this year and you'd have to think he'd be done.

I think Benji is safe for at least another season because Luai signing was apparently because he wanted to play under Benji. I'd say another failed season with Luai at the club will be Benji's unravelling.
Des I think is safe for at least another 2-3 seasons as well, 14/18 seasons he has made the finals as coach, has won 2 grand finals and made 5 overall. A poor first or even second season could easily be explained away by not having the right players at the club (Brimson, Tino and Fifita the only players that you could consider stars)
