NEW YORK – Two sparkling arenas. One All-Star city.

The NBA is bringing its All-Star Weekend back to New York in 2015, and the Knicks and Nets are putting aside a strengthening rivalry on the court to share it.

Barclays Center in Brooklyn will host the Rising Stars Challenge on Friday night and the skills events, highlighted by the slam dunk contest, on Saturday before the 64th All-Star Game goes to Madison Square Garden on Sunday, Feb. 15.

“To have two brand-new buildings, in effect, is what we have in support of New York City. It’s good for basketball. It’s good for the teams. It’s good for the NBA, and it’s great for the city,” commissioner David Stern said Wednesday at a news conference that included Mayor Michael Bloomberg and officials from both teams.

With two state-of-the-art venues after the construction of the Barclays Center, which opened last September, and a three-year renovation project at the Garden — both with $1 billion price tags — the league saw the opportunity to show off two of its best buildings in what it’s touting as a weeklong celebration of basketball.
