Welcome to the other side Bebop.
I think I agree with your (and Skates ) long term thinking. There may be no rush to move Miller (and i really enjoy watching the guy run the team) but we definitely have to switch gears from next year to a more developmental mode.
I could have seen us competing in the East with Miller, Iguodla and a stud PF like Brand- but now it looks like we will not be able to add a stud while we still have Miller. That means we are several players away- although those players may be on the roster, but 2-3 years from being ready for prime time (Young and Speights.)
If you figure in 2010 Iguodala, Thad, Lou and Sam will all be close to their prime, and Smith, Speights and Carney will all hopefully be contributors. That is the year we wan to to have a real vet star to add on to the line-up so that we can make a run. That means whatever move we make this year or next, we have to have an eye on what they team might be like in 3 years. Any time before then this team may be winner, but it is unlikely to be only one piece shy of a contender.
