Allen scored 25 points to lead the Celtics to a 105-85 win on Saturday afternoon. The Celtics put the game away in the opening quarter, taking an 18-2 lead behind nine points from Allen. Boston had beaten New Jersey by 32 points at home on Wednesday.
"From our vantage point, we didn't look at this as a game that would play out like it did in Boston," Allen said. "They have been playing well together and they've won some big games. We know first hand that if teams get out and get confidence, they can keep it going the whole game. We've lost a couple of games this year that way. It was a group effort, and a four-quarter effort."
"I was totally embarrassed by our performance," Frank said. "It starts with me and goes on to our main players. It was an embarrassing start to the game I decided to go in another direction."
Paul Pierce and Eddie House both had 13 points for the Celtics, while Kevin Garnett and Leon Powe each had 12. Rajon Rondo came close to a triple double with eight points, nine rebounds and 14 assists.
"It was a great start," Celtics coach Doc Rivers said. "It's one of the things we talked about. If you get off to a good start, it gives you a chance to play well the whole game. I thought the whole team was running well."
The defending champions have won four straight, all at the expense of the Nets and the Toronto Raptors. The Celtics have won seven straight from the Nets.
Carter understood Frank's decision.
"He made the call so I have to live with it," Carter said. "It's not easy to do but he felt like we weren't giving much to the team and he made a decision to go with a different unit. It's like that sometimes."
The Nets started 1-for-9 from the field. Carter, who had the only New Jersey basket in the run, picked up two quick fouls and was replaced by Hayes.
Boston led 29-15 after the first quarter, shooting 11-for-18 from the field. Allen had 14 of those points.
The Celtics led 68-39 at the half.
