It's a little like saying "Should the Bulls trade Loul Deng for cap space to make room to go after Howard?"
What? No
Or..."Should the Memphis Grizzlies trade Rudy Gay for cap space so they can make a great run at a free agent?"
No.
Are there any other young stars generally thought of as in the top 4-7 at their position signed to a very friendly long term deal that should be traded for nothing? Maybe Kevin Love? Kevin Durant just signed a deal. He's probably making money. If they just traded him then they could go after a good free agent.
