I am not an expert at trades or salary matching, but I am sure Morey is trying to land BOTH Dwight Howard and Deron Williams in Houston. Though other teams are trying to do the same, Houston has a leg up by having the money to spend and young, cheap players to trade. The way to do it with Williams being a Free Agent is trading for Howard and putting a few good pieces around to look attractive for Williams.
If Orlando would be willing, we could give up 2012 and possible 2013 draft picks + Dragic (or Lowry) (to take care of the Nelson situation) + Dalembert. Orlando would definitely remain strong at the PG position regardless of what Nelson decides and they get a cheap, defensive center. Additionally, they get a few picks to help the rebuilding process in Orlando. Most likely, I think landing Howard would force us to take a few bad contracts from Orlando (Turkoglu).
If we trade Lowry (or Dragic) and Martin to the Lakers for Gasol this would help the Lakers finally get the PG they desperately need and another outside shooter in Martin who is in the final year of his contract (needs to play great to get another fat contract).
Ideally, we get rid of Scola, but his dwindling stats might not be worth the money for other teams. I just don't see other teams willing to take him.
This is a high risk because now the Rockets officially have no PG, but this may be attractive for Deron Williams. Williams is from Texas and if I was him
I would have refused to play for any team except for the Houston Rockets for a low salary I'd like to return home, but the Mavericks are old and veteran-y with little excitement following the first round sweep by OKC. Plus they have Jason Kidd who just refuses to retire. The Spurs are already booked at the point position with Parker who played absolutely off the charts this year. If Houston is successful in getting both Howard and Gasol, then I think it would be the most attractive landing place for Deron Williams.
PG: Williams, Boykins?
SF: Parsons, Budinger, D. Mo
PF: Gasol, Scola, Patterson
C: Howard, Camby
This definitely takes away our depth, but makes us potentially Western Conference contenders as long as Spurs don't continue to play how they did this year.
