First thing’s first, I reckon Smith splits his time 70/30 between middle/hooker and Murray spends time throughout the game on the left edge to accommodate.
Duncan spends the rest of the non Murray time on an edge.
So between those 3 and Pete you get left edge, lock, hooker and bench edge sorted.
Hubner is a bench middle sub and injury cover for one of Murray or Smith going down. Likely takes that Havili spot on the bench behind the impact prop.
Aitken is your 14 utility.
Arrow and Tatola are 2 of your props, just need a third big man to round things out.
Le Blanc is first reserve (who in the NRL is still going to play a lot of footy).
Yes it’s a smaller pack, but I like the pedigree, work ethic, versatility and mobility.
