Over at Atlantic Yards Report, Norman Oder maintains that we should take the Nets’ pledge to move to Brooklyn in 2010 with a grain of salt:

Arena construction takes 24 months and can’t begin until the pending lawsuits are cleared…Even if the legal challenges end soon, it still would take a scheduled three years to reconstruct bridges on Carlton Avenue and Sixth Avenue, and it would be a very unwise move to open the arena with a major traffic bottleneck next to it. The Carlton Avenue bridge won’t close until January 16. Three years from then would be mid-January, 2011.

Given that the Nets originally intended to be playing in Brooklyn by 2006, Oder’s skepticism about the current target date doesn’t seem far-fetched.
