While the NBA players and owners continued their endless posturing and negotiating, there was some ball to be played in Brooklyn.

The NBA players’ union and the owners have been deadlocked in talks that extended beyond commissioner David Stern’s 5 p.m. to finalize a deal, while rookies like Kemba Walker and No. 2 overall pick Derrick Williams sit in limbo as to when they’ll make their NBA debuts.

“It sucks man,” said Walker, a former star at Rice High School. “It’s bad. I want to play basketball. But at the same time I completely understand the situation. I’m just trying to be patient and stay positive.”

Milwaukee Bucks guard Brandon Jennings, Greivis Vasquez of Memphis, Williams and Walker suited up Wednesday against alumni at Boys & Girls High School in the Bedstuy section of Brooklyn as part of Under Armour’s “Are You From Here?” Tour.

The squad played St. Frances Academy in Baltimore on Monday and plans to play at Lincoln on Friday. Mike Parker, brand director of basketball for Under Armour, said that the Indiana Pacers’ Lance Stephenson and Sebastian Telfair of Minnesota, both Lincoln alums, might play Friday.

But whenever players take the court, talk of the lockout follows.

“For me and Kemba especially, we’re rookies this season and it really is frustrating because we’ve worked all our lives to get to this point,” Williams said. “Not to be able to play is really frustrating. But we are anxious. We’re staying ready and hopefully we can get a deal done.”

Jennings said the tour has been a great way to have fun and stay busy turning the lockout. While some players have taken the chance to explore opportunities overseas, Jennings said he’s staying put. After high school, Jennings played a year in Italy, while waiting out the NBA’s age requirement, before being drafted by Milwaukee. He said the waiting must be even more frustrating for the Jennings and Walker, since they haven’t logged an NBA minute yet.

Jennings’ game didn’t seem to slow down any from the lockout. He was mostly guarded by Denver Nuggets forward Gary Forbes, a Brooklyn native, who starred at Benjamin Banneker High School but played with the B&G alumni Wednesday. Jennings set up a handful of alley-oops to Williams. But Jennings did most of his damage in the second quarter when he knocked down two impossible three-pointers, one of which was half-court buzzer beater on his way to a game-high 39 points. Team Under Armour won 100-91.

The pro squad was originally supposed to play against Boys & Girls high school team. But a PSAL league rule would not allow that. According to New York City Department Of Education spokesperson Margie Feinberg, “New York State regulation limits competition during the season among school teams in similar grades.” Lincoln will also put an alumni team on the court Friday.

Boys & Girls coach Ruth Lovelace said she was informed of the rule Wednesday morning, told the players at noon and made last minute phone calls to round up a team to play.
