One day after a 79-76 Game 3 loss to the Chicago Bulls, Brooklyn Nets players were frustrated, and Gerald Wallace was mystified about his role on the team.

"I couldn't tell you my role," Wallace said Friday at the team hotel. "I don't have a clue of what my role is on this team."

After scoring 14 points in Game 1, Wallace has been a non-factor offensively over the past two games of the series. He had five points in 25 minutes and was benched during crunch time on Thursday.

"I just think that we're going through a tough time right now," Carlesimo said. " That's what the playoffs are all about. We're all frustrated. And we have to.

"I have to do a better job of constantly defining roles and redefining roles so we can perform the way we're capable of performing."
