I think the trade today was a good one. Louis Amundson adds necessary depth and now the team can go get the scoring need that was never filled by the expectations for Brandon Rush.
I think the best move would be to wait until JR Smith becomes available in March.
Nick Young would be nice but would almost definitely be matched by Washington. Same for Aaron Afflalo. No need to waste money on a Michael Redd when Lance Stephenson can fill in until JR comes in for the playoff run.
I don't really see any other viable options unless the team trades a valuable asset. Everything that can be expended has been because AJ Price isn't worth a damn thing.
