In the second half of Friday's game at the FleetCenter, long-time season ticket-holder Mike Rotondi rose from his courtside seat.

He had a look of disgust on his face and his arms were raised to give a double thumbs-down.

At the time, he was responding to one of the evening's two brief classless chants aimed at Jason Kidd. But Rotondi, though he is endlessly encouraging to the home side, could just as easily have been characterizing the play of the Celtics.

So as we gather for Game 4 - what could be Game Last - of this Boston-New Jersey series tonight, let's just say there are a lot of people with something to prove. People on the court and people in the stands.
