Get a good backrower/lock option (still think Fifita is worth a long look) & add a front rower with 1st grade experience/capability (Corey Jensen/Jaiyden Hunt).
Then get your reserve half position sorted (Toby Sexton ideally but...Lachlan Ilias)
Then add your extra outside back depth (Junior Tupou along with Taylan May).
Very few gaps left after that.
Then it's sift through your KOE squad to remove guys with no future NRL level development & fill it with your development guys mixed with a 3-4 fringe 1st grade quality options so that when injury hits, you call up Royce Hunt instead of Charlie Murray.
