yi think the younger locals need to be persevered with or come 2019 - 2020 they will be all gone.
I think it is the middle bracket that need to be pruned out. The same situation exists at every Australian team.
Of the 2017 squad I wouldn't be worried about losing:
Ah-Nau
Day
Fou
Retallick
Siliva
Snowden
Shipperley
Reid
Maloney
Leafa
Jeffries
Cummins
Plus there are a bunch that have left that I wouldn't be worried about like
Meehan, Inman. Placid, Debreczeni, Fox.
The young, talented guys like Maddocks, McGregor, Tuipulotu, Goddard are important for the future and need to be there and you only want them kept out of the 23 by star players rather than journeymen who will never be outstanding Super Rugby players.
