There aren't that many games at the Olympics, so I would hope Brown and co have scouted all our opposition and will adjust their lineups to the suit the matchups.
Eg, against a weaker team we might try to overpower them with size by starting both Maric and Andersen. But on the other hand, against a lot of teams, a Maric and Andersen combo probably wouldn't be the best, because it would make for a very slow frontcourt.
Generally, I would have thought a Maric/ Nielsen combo and an Andersen/ Baynes combo would be best. In the first combo, Maric is your offensive target and Nielsen is there to play D, rebound and perhaps hit the odd mid-range shot if he gets open. With the second combo, you're looking to get Andersen some shots with Baynes on the offensive glass and stiffening the D down the other end.
Depending on your opposition, or who is playing well, you might use one combo a lot more than the other. At times, we might also need to go small and fast with Wortho if the opposing PF proves to agile for our primary bigs.
I don't think Newley has done enough over the past couple of years to warrant a starting spot at these Olympics. If he starts playing to the level we were all expecting of him by now, then I'll be the first to say start him, but until then, he needs to come off the bench.
I think Ingles and Mills will almost certainly start in every game, in which case I'd actually like to see Dellavedova play PG on offence and SG on defence. I think we will get the best out of Mills that way and that our offence will run much more effectively too.
I'd give Newley and Crawford good mins off the bench and use Gibson situationally - honestly I don't think his D is that much better than Crawford's and Crawford can actually shoot!
Barlow - I don't even know why he's on the team. Wouldn't play him at all.
