I know there are way too many trade ideas floating around on this board, but I really think that this one has some merit.  This trade with the Portland Trailblazers would add size, length and shed some money on the long run for the Warriors as well as give Portland very reasonable pieces to move forward with.

Summary:

Warriors trade Monta Ellis and Andris Biedrins to Portland in return for Nicolas Batum, Andre Miller and Marcus Camby

Why the Warriors do this:

We are in big need of PG depth, interior presence and perimeter defense.  Miller (backup PG), Camby (Center) and Batum (SG) are almost perfect fits for our system. and address these three needs.

Why the Blazers do this:

They clearly will need a longer term answer at center based on Oden's injury history and Ellis could take over the point there with true options on the wing (Roy) and the paint (Aldrich).  Beans could just stay back and play how he likes (rebounds and help defense).

Doubt this would really happen, but I think that both teams would improve now and in the future with this one.
