While I for the most part agree with you we could get very close in getting that 'allstar/superstar' if Neil was just willing to listen to offers and trade CJ. Now I don't know who that player/s is but they are out there.
Um..... Napier, Connaughton, Turner, WB4. Uh......... We use one of our trade exceptions to go get a SG. Eh......... Just a couple of options the Blazers could explore.
EDIT: Also you are assuming a SG wouldn't or couldn't be a part of the trade for CJ.
