Trading for Murphy would not be such a good idea, we would be giving up more than we would be getting. His expiring deal is worth way too much for us to make a deal that ends up benefitting us.
Brandan Wright is unfortunately in NJ now, so he cannot be involved in these trade discussions.
Dorell Wright is the ideal. GS would be saving more long term money, and they get a back up point guard that is better than whatever Acie Law is dishing (or trying to dish) out. He has been a stud starting for Golden State. However, his defense is not ideal. Fortunately for the Celtics, though, is i believe in Doc and Lawrence Frank and their team defense that has made even phantom defenders step it up. I would not mind throwing Von Wafer in a trade for Dorell either. Dorell makes a lot of what Von does redundant, and Von has some value after showing flashes of talent recently.
Plus, if we traded with Von, we would have an open roster spot for a bought out free agent, like Murphy.
