Ineedmore, its not about keeping your entire roster, its about hanging onto your key players.
The successful teams have done that:
Hawks - Sav, Campbell, Davidson (developed Tragardh too)
NZ - CJ, Penney, Boucher and until this year, Ronaldson and Forman.
Perth - Martin, Redhage (and developing Weigh and Wagstaff). Before that they had Catt and Rogers around for quite awhile.
Melb - just had cleanout, but if you look at the perennial powerhouse they were, it was anchored by Anstey, Mackinnon and D-Mac.
Kings 3-peat - Nielsen, J Smith, CJ Bruton
Adelaide - Going back to ancient times now our team was built around Maher, Cattalini, Rees, Brooks and Mee.
A three year plan doesn't mean you choose your roster on day one and keep the same 10 players for three seasons!
It means over three years, you identify your core players, develop them, bring in the right complementary pieces and hopefully develop a culture of good habits and attitudes. The culture is important, because when injuries occur, young guys that have been around the team tend to plug into the lineup and succeed. Ever noticed how good teams seem to keep churning out the best rookies too?
Goorjian was successful in this way, because he could take young guys and get the best out of them year after year: Mackinnon, J. Smith, Ronaldson, Worthington... I'm sure someone will come up with others
He didn't just rely on getting great imports every year!
