I wouldn't be at all opposed to sticking w/ Bass - it works for now. Especially if Danny finally gets this team a bench. Terry, Green, Sullinger, Steimsma, could provide enough D and offense to turn this team into defensive version of the Spurs with depth and limited minutes for our vets.
I do feel, as I can see other do too, that a quality starter at the 4 would take us from dark horse contender to legit top 3 team. Josh Smith may be a pipe dream with the recent moves in ATL, Jefferson or Scola would be very helpful and very addable pieces. With all the moves being made by the Nets it would be nice to ensure we stay well above them and Philly in the Atlantic. Still waiting for that big move... (Yes I know, it may not come)
