Bruce Ratner, like Mikhail Prokhorov and Jay-Z, will have his own suite at the Barclays Center and is promising an 18-year-old South Sudanese boy a seat on Opening Night. Ratner and his political analyst sister Ellen have "adopted" Ker Deng, a blind, torture victim of Sudan's civil war. They met Deng last April and brought him to New York, quietly providing him with eye surgery, schooling and a caretaker. Ratner's gone public because the boy's visa is running out. "If you are still here, I am going to take you to the first Nets game and explain everything," Ratner told Deng recently.
