Buried in a Brooklyn Eagle story on economic development in Brooklyn is a quote from the city's deputy mayor, Robert C. Lieber, that suggests Barclays Center might not be ready by Opening Night in October 2012. "You will see the first game played at the new arena at the end of 2012 or no later than 2013," Lieber told a group of construction execs last Tuesday. The Nets' Newark lease be extended for up to two years. For Barclays Center to be open by October, it must be completedy by July, then undergo a four-month "commissioning".
