Here are the facts: The Barclays Center and the Brooklyn Nets are split between three individuals: developer Bruce Ratner, Russian billionaire Mikhail Prokhorov, and Jay-Z. Ratner owns 55 percent of the Barclays Center and 20 percent of the Nets. Prokhorov owns 45 percent of the arena and 80 percent of the Nets. Hov has a fraction of one percent of each. But he's the name, Brooklyn born and raised. His presence can be felt in the advertising, in the expensive Champagne room, the Vault, and of course, in the schedule: He's the opening act. Before any basketball is played, Jay will rhyme there.
