LURING LEBRON As the Knicks and the Nets, along with seemingly half of the N.B.A., prepare to woo LeBron James near his northeast Ohio home, advertising campaigns have sprung up across billboards and basketball courts, a larger-than-life homage to the larger-than-life James. In Harlem, painters were completing a portrait of James, wearing a Knicks uniform, on the surface of the Rucker Park basketball court. Nearby are the words: “Harlem loves you LeBron.” As the world awaits, the whole country is attempting to get Lebron.
