NBA commissioner David Stern said on Thursday night that he would like the league's coaches to be able to challenge late-game calls using a replay system like the NFL's.

Stern discussed the use of more replays, the Nuggets-Mavericks series and fouling in a news conference prior to Game 6 between the Lakers and Rockets.

"There are two things that I'm more interested in," Stern said. "I'm a little disappointed that the competition committee hasn't been a little bolder in instant replay. The other thing I want to study is security in the broadest context, and how we on the one hand maintain the intimacy that is our game, which I think sets us apart in a good way and brings our fans closer, with making sure that our fans can come and continue to enjoy our game the way they have."

He added that he would like coaches to risk losing a timeout if the call is not overturned, which is the format used by the NFL.

"What we're struggling with ... we want to have a set of rules, we want to call it the way they're written, we want to have a game called the same no matter who's reffing it, and we want to assure that we get it right. Against that, we struggle with the problem of to get it perfectly right, put 16 cameras and take four hours to play the game, we can't do that and we won't do that. So what you're seeing is us move slowly to more replay. And I think this is a good time to look at it again. And it may happen and it may not happen."
