WALTHAM — Doc Rivers  has told his team time and time again about ‘Old School’ NBA, especially as it relates to the playoffs.
But Saturday night, when his team takes to the floor against the desperate Orlando Magic , he doesn’t want his team to get caught up in what is likely to be a physical game with Dwight Howard  and the Magic. He also doesn’t want his team to get pushed around either as the Magic try to come in and physically prove to the Celtics  they haven’t checked out of the Eastern Conference finals, despite losing the first two games on home court.
“They should be feisty and we should be, too,” Rivers said following a high-spirited Friday practice, their final before Game 3. ” It’s the playoffs. It’s Game 3 and we’re trying to defend our home turf, now and they’re trying to take it away. There’s every reason it should be feisty and it will be and we should be feisty, too.
“Obviously, you want to always keep your head but that doesn’t mean to back down. That means you want to play with composure, play with intensity and you’ve got to play hard.”
Paul Pierce  and Kendrick Perkins  agreed with Rivers, saying they are expecting a ‘feisty’ Orlando Magic team for Game 3 Saturday night at TD Garden. The Celtics lead the Eastern Conference finals 2-0 and can take an overwhelming 3-0 lead with a win, a deficit no team has ever overcome in NBA playoff history.
“It could get feisty in there. You have to expect it,” said Pierce, who was still bearing a pair of scratch marks on his forehead above his left eye after being decked by Dwight Howard in the second quarter of Game 2 on Tuesday night.
“Doc always say the bigger man walks away,” added big man Kendrick Perkins, who will once again be assigned to Howard. “You just have to go out there and play, play Celtics basketball.”
