Celtics point guard Rajon Rondo hinted after last week's loss to the Atlanta Hawks that some changes needed to be made in the Boston locker room, but are there issues growing behind closed doors in the land of Ubuntu?

"We gotta make a change and do something about it quick," Rondo said after the Hawks capped a four-game season sweep of the Celtics Friday at Philips Arena. "Not a trade or anything, but just making some changes in the locker room, amongst ourselves. Every guy has to look in the mirror and hold themselves accountable."

Asked to elaborate his thoughts this week, Rondo suggested some players might have individual agendas, telling the Boston Herald's Steve Bulpett:

“I can’t really elaborate on it too much, but I think we’ve just got to be a team with no agendas,” Rondo said. “We’ve got to play unselfish, you know? That’s on defense and offense. You’ve got to want the best for the next man out there regardless if you’re in the game playing well or you’re out of the game not playing well.”

Asked if he and the Celts had tried to clear the air on this, he said, “We haven’t really been talking about it, but you’ve just got to know.

“In the locker room, you can feel it,” Rondo added. “You don’t feel like it’s the same continuity and camaraderie in the locker room as it was the first year. The first year, it was a crazy spirit in the locker room. But now it doesn’t feel the same. It’s not the same right now. We’ve got to find a way to get that back somehow, some way.”

Is the Celtics' locker room divided? If nothing else, Rondo's comments are the most condemning of what others have been saying. Celtics center Kendrick Perkins stressed after Sunday's loss to the Lakers that the players in Boston's locker room are behind each other more than ever.

“I don't think it's anything," said Perkins. "I know a lot of people are turning their backs on us, which is cool, that's fine with us. We just gotta keep believing. Everybody’s got to be accountable for their actions... Don't point the finger, everybody look at themselves in the mirror and go from there.

"We’re cool, we real cool. There's no beef. Guys still talk, laugh, joke -- we’ve all got each other’s back. That’s one thing you don’t have to worry about in this locker room, especially with [Kevin Garnett], Paul [Pierce], Ray [Allen], and [Rasheed Wallace] in here. Guys will stick together."
