Realistically with West's injuries we need Daniels or Nate as a backup for Rondo, plus we need Wafer to cover SG. Wafer's play of late makes a trade where Nate goes out much more possible. I'd love to see a combo forward brought in, if the team can find someone that needs an extra guard. Nate can be a good fit playing PG next to a ball dominant wing that runs the offense... (like how Ben Gordon looked great when McGrady ran point and set things up.)
Since I'm obsessed with Marvin Williams, what about this (assumes team is comfortable with the returns of West and Perkins.)
http://games.espn.go.com/nba/tradeMachine?tradeId=2cpova7Assuming Bibby could be bought out for something reasonable. Maybe with some cash from BOS to ATL and a second rounder from ATL to BOS?
ATL could play Zaza and JO at center. Move Horford to PF and split Smith at the forward spots. JJ starts at SG and plays some SF, Jamal Crawford is the first wing off the bench. Nate and Teague split the point (with Nate starting.) ATL figures out what to do with Bradley.
BOS buys out Bibby to keep this close to neutral from a rev perspective (Bibby would probably take a pretty decent buyout since he may not see any of next year's salary and can probably latch on with a contender as a backup PG, the C's would then save on luxury tax this year.) They get a second round pick which makes up for AB (at least in my opinion.) The only downside I see is that Marvin is signed for multiple years, meaning the C's ability to go after free agents 2012.
New depth chart is (assuming everyone is healthy):
Shaq / Perk / Semi
KG / Baby / Luke
Pierce / Williams
Allen / Daniels / Wafer
Rondo / West
With starters Shaq / KG / Pierce / Allen / Rondo and a bench Perk, BBD, Williams, and West. West covers both guard spots - Williams covers SF, with Pierce able to play some SG. Baby plays PF and some C, Perk plays C.
