I don't think you need to worry about losing a PG or small guard Paul.
Neither of Mills or Delly are natural playmakers (Delly has the head for it sometimes but struggles to see the entire floor and can get passing tunnel vision, and is not great in a hand-eye coordination sense) so I'd be more worried about losing Ingles or Bogut (or to a lesser extent Jawai: an excellent passer but won't be on the floor much).
Also I'm out on Goulding as a Boomer. I wanted him in for his fire and cockiness (two things the Boomers really lack of late) but he's a streaky scorer who doesn't look comfortable at that level. He needs volume in terms of ballhandling and shots to be effective, and he's not going to get that many touches in international ball. I'd rather have a guy like Blanchfield who is a better shooter, better rebounder, better defender, more athletic and doesn't need lots of ball to get going. Blanchfield can get you 16 points and only touch the ball a handful of times all game, and he is getting better every day as a finisher. We need more guys who can stand in the corner and knock down shots.
Blanchfield will play his way into the Boomers this year, he's already the best player at Melbourne.
This is my ten, it is in line with how modern basketball is played, it has multiple guys who are world class athletes and who can play multiple positions. Motum, Anderson and Bairstow are out. They give you nothing. Neither guy can defend the four spot because they're too slow, and they're not good enough shooters or finishers to give you a plus on the other end. Anderson is the best offensive player of the three but I don't want to have a shot-happy big who shoots long twos at an average clip as his go-top weapon.
Broekhoff, Ingles, Newley, Blanchfield
Whoever is 11 and 12 is irrelevant because you can't win one of these tournaments going 12 deep unless you are the USA. So name whoever but that's our rotation.
This team would blow the team Lemanis is going to pick off the floor. Just the same way that every Euro team who can go big or small is going to blow us off the floor in Rio when we carry half a roster of 7 footers who can't shoot or run.
