PHILADELPHIA -- Celtics coach Doc Rivers looked frustrated but not defeated after the Celtics lost Game 4, 92-83, Friday night.
"I thought they came out and became more physical, and I thought we got into that instead of playing basketball," said Rivers. "I thought in the first half the execution was beautiful. We did all the right things. In the second half we just didn't do it."
The Sixers had 17 offensive rebounds to five for the Celtics. Boston had 17 turnovers. Philadelphia shot 36 free throws. The Celtics blew a huge first-half lead.
"Everything we did was the prescription that you don't do," said Rivers. "We took it away from ourselves."
On the other side was Sixers coach Doug Collins, who was impressed with the heart of his players.
"Our guys are pretty amazing," said Collins. "They really, really are."
Rajon Rondo tried to explain his team's almost seven-minute drought from the floor in the third quarter.
"I've got to do a better job of slowing us down, getting us in the right sets, and getting guys to execute offensively," said Rondo.
-- Andre Iguodala was calm and collected after the win.
"We don't have as much experience as them," said Iguodala. "But we definitely have a lot of experience in a lot of situations we've been through. This is a good win for us. It puts us in a better place.
"We probably shot as poorly as we could shoot. ... Whether we're making shots or not, if our defense is standing strong, we'll be in a good position."
