That's what maley and free are supposed to be doing
Maley is 197cm and more of a forward/ruck. Was never going to be a full time ruck option. Free will be delisted by the end of the year. CCJ has shown he isn't up to being a full time ruck, and will probably struggle coming back after an achilles.
Moyle or Bryan would absolutely put pressure on Xerri and give us really solid depth. Both of them would back themselves in to be the number 1 over X too.
