TC, good call mate, Goorjian is a good coach, but he has benefited from having very good players at his disposal most of the time.
Andy, hate to pour cold water on the idea of Aussies getting a go at one of the best franchises in the NBA, but none of those guys you mentioned are going to the Spurs (except at a stretch Wortho if the Spurs need a cheap replacement for Bonner or something).
No way Bogut would co-exist well enough with Duncan to make his salary worthwhile for the Spurs. They are much better off with a cheaper centre who can make the outside shot and thereby open up the middle for Timmy D.
Mills won't go to the Spurs because they already have Parker, and George Hill is looking pretty solid off the bench too. Better for Patty to go somewhere he has a shot at a starting job in a couple of years (though that seems unlikely unless he can sneak into the first round).
Actually, now I think about it, Atlanta would be a good team for Mills to go to! He'd have to beat out Acie Law, but I reckon he could do that easily and play as Bibby's backup on an athletic, up-tempo team that will be even better in a year or two when Bibby is ready to hang em up!
I'm afraid to say Ogilvy is not on any NBA teams radar either. Draft Express has dropped him from their 2009 mock draft entirely, and from what their scouting report said, he probably does not have the athleticism to succeed at that level. This is good for the NBL though, because I have very little doubt he will kick some ass down under.
As far as Brett Brown goes, I'm more interested in what new stuff he can bring to the table for Australian basketball, because we need it really badly. (See your comment about shuffle offence, anon's comment right before this one, and several others by me about team strategy on other threads).
