OK, guesses at the points system. Brett is a 5. Nash probably a 6 or 7. Ng is a 4. Oscar and Jacob (Jacob is a 7 brought down I think) are 5s. Rychart and Cat are probably 10s.
5 Maher
10 Cattalini
10 Rychart
7 Nash
5 Holmes
5 Forman
4 Ng
That's 46. We've got 20 to spend on 3 players. You'd have to assume that Rees is a 5 max after his last season where the Bullets barely played him. 15 to burn. 10 on an import. 5 to go.
Now, I think that Nash last season was actually a 6 and so was Williams. If Nash is a 6 this year, they could retain Williams instead of Bell. If they got Bell as a rookie, they're definitely under the 66 points.
I think money is definitely the deciding factor. I'd say that they might've spent more than they'd prefer on Rees, but then he might've come to his senses and realised that he was barely kept in the game by Brisbane, and the market right now is pretty tough. Most rosters are getting close to full, and players like Axel Dench and Derek Moore are still up for grabs it seems.
