WALTHAM — In the hours before Game 6, Terrence Williams reminded everyone of the animosity between the Celtics  and Knicks in this series.
“I always wanted to say this, that’s playoff basketball,” Williams said at Friday morning’s shootaround in Waltham. “Before I got here, I heard these two teams were rivals so you don’t expect anything less. But at the end of the day, it’s basketball. I think everything should be left on the court. Nothing should be escalated off the court like last game at the end of the game. Stuff like that shouldn’t happen but it’s playoff basketball.”
The back-up guard doesn’t think either team has any tricks in store for Game 6 at TD Garden. Williams made a point to once again bring up the Knicks funeral wardrobe before Game 5 at Madison Square Garden, and explained why that bothered him.
“No, there are no surprises,” Williams said. “At this point, I don’t think either team likes each other. We’re all for our guys and they’re for their guys. When people wear all black and say it’s a funeral, a lot of us have people that died in our own personal lives. That’s not really something funny. That’s not something to play with. You can say you’re going to end the series in New York but not [call it] a funeral. We know we don’t like them and we know they don’t like us.”
That bad blood was countered when Jordan Crawford verbally attacked Carmelo Anthony at the end of Game 5, giving the Knicks some ammunition in the war of words. Crawford didn’t play in Game 5 but Williams did. It was Williams, along with DJ White and Chris Wilcox , who was at the center of trying to keep Crawford away from Anthony and the Knicks.
“I was there, yeah,” Williams said Friday morning. “I don’t really remember. I put out of my mind. As you guys saw, I was trying to be the peacemaker. I grabbed Felton. I don’t want that to escalate. I don’t really remember.”
Has a message been sent from coach Doc Rivers  and the staff about keeping the mouths shut before and during the game?
“I don’t know if it has or hasn’t,” Williams said. “It doesn’t really matter. At the end of the day, we’re going to compete. If there’s a funeral, then there’s a funeral. If there’s fuel to the fire with that, then it is what it is but you don’t really have to have that conversation because we’re not little kids. We’re professionals. We’re going to try and handle our jobs every day.”
Williams was the only Celtics player to talk Friday morning as the team prepared for the 7 p.m. tip at TD Garden.
