Let's also remember there are only 5 starters on a basketball team, and 15 players max including walk ons, Managing a basketball roster isn't like managing a baseball or football roster. When you hvae a talented basketball team a lot of times you are one guy away from being a championship quality team. In baseball GMs really have to grind. Look at Brian Cashman, he was forced to send down the very talented 2b prospect Rob Refsnyder because the alternative was to designate for assignment one of Stephen Drew or Brendan Ryan, both of whom suck, but you don't DFA a guy who sucks and potentially leave yourself no coverage at two positions if someone suddenly offers you the world for Refsnyder. Ozzie is correct to use the word grinding but it's really just a pure numbers game and the coaches basically know who is going to be getting big minutes and who the role players are. It's not like baseball where you have more personnel, more rules and injury issues that can really screw your team if you leave it short in any one area. In hoops you just need 7 guys who can ball and if they are healthy it will be fine.
A core around Adams, Gilbert and Larrier should be easy to build. You already got one guy who looks like a beast on the boards in AAU, now get a shot blocking center and you are all set.
