Practice: C's reflect on Game 4 loss

WALTHAM, Mass. -- Two of the bigger topics on this day were Avery Bradley's ailing left shoulder and Kevin Garnett's offensive aggression, but here are a few more nuggets from the Celtics' media access before the team practiced Sunday afternoon at HealthPoint:

* Film never lies: Celtics coach Doc Rivers said it's not difficult to show his team what went wrong in kicking away an 18-point lead during Friday's Game 4 loss in Philadelphia. Just hit play. "It’s easy to teach because it’s visual. The film, as they say, never lies. You can visually see. Listen, (the 76ers) made shots that they had to make. They forced turnovers that they had to force. But a lot of it was our doing. More on the defensive end than the offensive end. We couldn't run, we couldn’t get into sets, because they scored every single time, for the most part. Or we turned the ball over. Or they got an offensive rebound. But our defensive breakdowns were partly because they did a pretty good job of moving the ball and getting the ball side-to-side, and partly because we completely lost our discipline."

* Small lineup was big issue: After Philadelphia had success rallying against Boston's small lineup on Friday, Rivers admitted the team probably erred in not putting Brandon Bass back on the floor with the starters. "Honestly, if we made one mistake, we should have gone back to Bass," he said. "In the first three games, our small lineup was a better lineup than our big lineup. Statically, in Game 4, the big lineup was better; the big lineup was what got us the lead. The big lineup at the beginning of the third got off to a good start. And both times when we went small, it hurt us. So that’s something as a staff we have to recognize, and it’s a tough call. We’re going to have to make a call each game, it looks like, and there’s no right or wrong to it. It’s going to have to be a gut feeling and I hope when we make it, we make the right one."

* KG: Focus on rebounding: The Celtics were outworked on the glass in Friday's loss, the 76ers owning a 52-38 edge thanks in large part to 17 offensive caroms (which they used to turn into a modest 12 second-chance points). Asked what he took out of film review, Garnett said, "Rebounding, second-chance points. We control that, we controlled our destiny in that game and we didn’t do that." Garnett admitted the 76ers have created matchup problems when they put Thaddeus Young at the power forward spot. The Celtics have countered by going to their own small lineup, but that's what hurt them on the glass in Game 4.

* Cleaning up the spilled milk: Celtics captain Paul Pierce said Boston won't dwell on Friday's Game 4 loss. "It’s over. Milk is spilled, gotta clean up, move on to the next game. You can’t let it frustrate you, can’t dwell on the past. It is what it is. The series is 2-2, obviously we have to go back to Philly. But we've got to take care of business at home."

* The officials? Not going there: The Celtics watched the 76ers own a 36-19 edge on free throws in Friday's game, aiding them in rallying back from an 18-point hole. Given the chance to gripe about the officiating, Rivers kept his money in his wallet. "I’m a fan of the officials; I love the officials," he said with a smile. "Really, listen, we had a big lead and all of a sudden they started to go to the line, which allowed them to get back in the game. We have to stop fouling. Or we have to get fouls. One of the two."
