The Bulls' Nate Robinson might not have anything to say after the game Monday night against the Boston Celtics at the United Center. And that's saying a lot for one of the NBA's chattiest players. If injured point guard Kirk Hinrich is unable to play, Robinson will start in his place. He likely will use all of his energy guarding Rajon Rondo, one of the league's best point guards. Hinrich left the Bulls' 87-80 victory Saturday over the Minnesota Timberwolves with a strained right hip in the second quarter. Though he'll be re-evaluated at the shootaround Monday morning, he figures to miss the game. Coach Tom Thibodeau called Hinrich day-to-day. "I'm not trying to make it about me and him [Rondo]," Robinson said. "This is a team. We're trying to win the game. We're trying to beat the Celtics. It's not me versus Rondo. It's the Bulls versus the Celtics."
