GREENBURGH, N.Y. – Though he has not spoken to anyone from the Indiana Pacers, Lance Stephenson is well aware of Larry Bird’s disappointment with his arrest.

Stephenson says he heard about Bird’s strongly worded statement that was critical of his actions and plans to speak to the Pacers president.

“I’m just going to try to stay focused,” Stephenson said Tuesday at the New York Knicks’ training facility, where he joined other rookies getting photographed for their Panini trading cards. “I’m going to talk to him, see how he feels about it and I’m going to move forward from it.”

Stephenson, 19, was arrested Sunday in New York on assault, menacing and harassment charges. Prosecutors said the Pacers’ draft pick pushed his girlfriend down a flight of stairs, then grabbed her and hit her head on the bottom step.

On Monday, Bird called the arrest “very disappointing to the Pacers franchise and to me personally.”

In Indianapolis, the Pacers introduced their newest acquisitions, point guard Darren Collison and veteran forward James Posey.

Collison had an outstanding rookie season in New Orleans before being traded to Indiana last week. He averaged 18.8 points and 9.1 assists in 37 starts for New Orleans last season while All-Star Chris Paul was injured.

Collison said Tuesday that he expected to back up Paul for years and was surprised by the trade. Now, he’s the man.

“I didn’t think it would come this fast,” Collison said. “I could only imagine, in my eyes, playing behind the best point guard in the league and learning from him for so long and learning a lot from him.”

Collison will join forward Danny Granger and center Roy Hibbert to form the team’s young nucleus. Granger averaged 24.1 points last season and is on the USA team that will play in the world championships in Turkey. Hibbert emerged last season as a rising star, averaging 11.7 points and 5.7 rebounds.

Posey wants to make it tough for the Pacers coaches to sit him down. He has won championships with the Miami Heat and Boston Celtics and wants to bring his winning approach to Indiana.

“I’m going to come in here, lead by example,work hard and compete at a high level,” he said. “At the end of the day, it’s about working hard and winning basketball games.”
