PHILADELPHIA — Over a late-night meal on Wednesday night in Boston, after they were blown away 105-86 by the 8-1 Celtics and had lost for the third time in their last five games, Deron Williams was talking with a teammate.

The root of the Jazz's woes was the topic of discussion, and the subject was as sore as when the dentist must dig deep into a canal.

"A lot of it's a little bit of selfishness," Williams said Thursday. "When we build leads, we start looking for our own shot and worrying about scoring instead of getting stops.

"We went to dinner last night, and a couple of us were talking.

"We looked at Boston, and, you know, Paul Pierce has 10 points (actually 13 by game's end Wednesday), K.G. (Kevin Garnett) has 10 points (actually 18), Ray Allen has 10 points (actually 15), (Rajon) Rondo has 14 points, somebody else has 12 points — and they're on the bench happy," the Jazz point guard added. "They don't care who ... gets the glory. They just want to win. Until we figure that out, we're not gonna be a good team."

Williams was so down after Wednesday's game that he used his Twitter social networking account to vent.

"We got to change something bc (because) what we doing ain't working right now!" he tweeted. "Don't know what but something?????"

Before practice Thursday morning at Boston's Suffolk University in advance of tonight's game against the Philadelphia 76ers, Williams expounded.

"Not like trades or anything," he said.

"We just have got to change something. We've got to, you know, find something that works, whether it's lineups or whatnot. We've got to do something different.

"I didn't mean to tweet it was the end of the world," Williams added. "Just, we've got to do something. I know the fans watching, I know the fans sitting at home, they're not happy with us right now. I'm not happy with us either."

In the wake of it all, Jazz coach Jerry Sloan said Thursday that an opening lineup change will be considered for tonight's game vs. the Sixers.

He did not, however, commit to making a switch, or say which possible change was being considered.

"We'll see what happens," he said. "We'll discuss it with our coaches. We've already discussed it. We discuss it all the time."

Sloan benched starting power forward Carlos Boozer in favor of backup Paul Millsap early in both the first and third quarters of Wednesday's loss to the Celtics, and he replaced starting center Mehmet Okur with backup Kyrylo Fesenko early in Wednesday's third quarter as well.

Asked if he'd consider replacing Boozer with Millsap in the starting five, Sloan said, "I don't know. I don't know who it will be. But I'll have to make that decision when it comes down to it."

Whatever happens, Williams just hopes something is altered.

"It's definitely concerning," he said.

"All these losses we've had have been bad, and this early in the season it's not good for us, because in my previous four years, we started off with pretty good records, if not great records.

"We fizzled as the season went. So, if we continue that trend we're not gonna have a good year."

At the eight-game mark of the past three seasons, the now 3-5 Jazz have been 6-2 or better.

With a lineup that's essentially the same as this season, that seemingly has Sloan stumped as to why his team has been so inconsistent this season.

"It's amazing," he said. "You see them play so well together for a period of time, then all of a sudden it changes. They lose their focus, or whatever."

But why at some times and not others?

"If I knew a reason, if I had an answer, I'd solve all our problems," Williams said. "But I don't."

Asked if he thinks there is anything malicious behind the dispirited play of any of his teammates, Williams indicated otherwise.

"I would hope not," he said.

"We've just got to have a better effort from everybody," Williams added. "Me on down to Kosta (Koufos), Fes (Fesenko). I mean, a better effort."
