2015 NBA All-Star Game will likely be played in New York, but where? Barclays Center or Madison Square?

The key stumbling block will be which state-of-the-art arena — the Nets’ new Barclays Center or the Knicks’ refurbished Madison Square Garden — will host the game

The 2015 NBA All-Star Game almost certainly will be played in New York. The only question remaining for the Knicks, Nets and the league is in which arena the game will be played.

They are working with the league to jointly host All-Star Weekend, which would mark the first time the event would be held in the metropolitan area since it was played at Madison Square Garden in 1998.

“There is progress in that the teams are working together ... recognizing that it’s in both of their interests to create a basketball festival-type atmosphere around All-Star in New York, and so things are going well,” NBA deputy commissioner Adam Silver said this week.

The key stumbling block will be which state-of-the-art arena — the Nets’ new Barclays Center or the Knicks’ refurbished Madison Square Garden — will host the game.

It’s likely the solution will feature one building playing host to the Saturday night festivities, including the 3-point and Slam Dunk contests, while the other will host the game Sunday night.
