I think we'll always be competitive in the 20's it's just about being able to manage the season better. Next year, they won't be so disrupted during the rep. season I imagine.
All those players you've listed have indeed graduated. Other players confirmed for the senior squad are Mitchell Frei, Jordan Kahu, Aaron Whitchurch and Lachlan Maranta. I'm unsure what Arthur Brown, Matt Smith, Jarrod Wallace and Daniel Wallace are doing either.
Current Squad Members who are still eligible...
Mboya Adams
Daniel Alvaro
Matthew Berwick
Caleb Binge
Chris Binge
BJ Burgess
Stephen Coombe
Cameron Cullen
Mitchell Frei
Louis Frisby
Bryce Hegarty
Jake Kelly
Jerome Leedy
Benn Malley
Lachlan Maranta

Aaron Whitchurch
I expect to see Francis Molo (Prop), Kodi Nikorima (Halfback) and Brandon Lee (Backrow) join them next season.
