With four major sports complexes crowding a 30 mile radius, and another on the way to Brooklyn as part of the embattled Atlantic Yards project, owners are now facing the sobering prospect of one day fighting to fill nearly 100,000 seats, 365 days a year. Mark Rosentraub, a professor of sports management at the University of Michigan, tells the Times, "The market is saturated... Five arenas is not going to work. I don’t think four works, even in a market as large as New York. There’s competition in every direction and there aren’t enough events." Of course, there's been heated debate for years over whether these government-subsidized stadiums—often sold as snake oil panaceas to foundering regional economies—actually contribute much to the community. (Here's one great article on the subject.) Now arenas are hemorrhaging money across the country, the Times reports. But this is New York, and there's always room for one more! Developer Bruce Ratner, demonstrating a vampiric ability not to die from a thousand cuts, scored some major victories last week, and is rushing to break ground on his Brooklyn monstrosity before the end of the year.
