The Nets’ regular-season debut in Brooklyn will have to wait. The New York City Marathon, however, is good to go.

With mass transportation still crippled in the aftermath of Superstorm Sandy, New York Mayor Michael Bloomberg asked the NBA to postpone Thursday’s highly anticipated opener between the Knicks and Nets at the Barclays Center, and the league agreed.

“It’s a great stadium, it would have been a great game, but the bottom line is: There is not a lot of mass transit. Our police have plenty of other things to do,” Bloomberg said at a news conference Wednesday.

The Barclays Center sits above the Atlantic Avenue subway station complex which hosts nine subway lines and a Long Island Rail Road station, and was expanded as part of the $1 billion arena’s construction.
