Well, they just traded Rudy Gay and Stromile Swift for Shane Battier. Last I checked, Tracy McGrady is still on the roster. And Peja probably wants more money than we can offer. So no.
After trading gay and swift for SB, rox has no money to sign him and no assets to trade for him. Rox is dead. Yao should demand a trade to lakers.
This trade no effect on our cap flexibility, even if this horrible trade wasn't made we still wouldn't have been able to sign him.
