Jrue Holiday has made some fourth-quarter mistakes.

Just ask him.

He's definitely the player with the most upside, a youngster who'll soon be confident and savvy, but as of this moment he knows he's making some late-game errors as the 20-year-old point guard for the 76ers.

Holiday was asked what he most needs to work on. "Taking care of the ball in the fourth quarter," he answered. "I'm young, I know, I hear it from everybody, but that's definitely it."

Regardless of mistakes, Holiday is one of the NBA's best young point guards, as evidenced by his selection to the Rookie Challenge and Youth Jam. The NBA announced the rosters for the rookie and sophomore teams on Tuesday night. Holiday was selected to the latter.

The league's assistant coaches picked the players for the game, which will be played Feb. 18 during NBA All-Star Weekend in Los Angeles.

Sixers rookie Evan Turner, the No. 2 pick in the draft, did not make the rookie team.

On Tuesday, for the second straight practice, Sixers coach Doug Collins addressed a new wrinkle he's inserting into the Sixers' offense: moving Andre Iguodala to point forward, allowing Holiday to play more off the ball.

The Sixers practiced at the Philadelphia College of Osteopathic Medicine before taking a bus to New Jersey for Wednesday night's game against the Nets.

After practice, Collins said he is comfortable with four guys running the point: Holiday, Iguodala, Turner, and Lou Williams.

"Those guys have been interchangeable all year long, so when I say this, it's not something we're doing for the first time, we're just going to do more of it," Collins explained.

Holiday said that even in the new scenarios he would still be a "playmaker off the ball."

"It takes a lot of pressure off of me," Holiday said. "I think it helps me out."

Iguodala said this new layer of offense would make the Sixers even more difficult to scout. Considering how many options and how varied their offensive style already is, this will be another option for opposing defenses to assess and then digest.

"Sometimes teams can watch film and see it's the same thing over and over and they try to adjust to it," Iguodala said. "That gives them a different look and then they have to figure out what scheme they're going to use when I'm bringing it up."

Collins stressed that this isn't a revamping of the team's offense, but merely a tweak that might produce small dividends. Collins said Tuesday's practice was the team's first long, productive practice since Christmas Day in Denver.

"We moved a lot of guys around," Collins said of the multiple looks.

The team's leader? You may sense you've heard this line before, maybe in the last few years, only to watch the Sixers deteriorate before your eyes: Iguodala is embracing his role as leader.

The truth is we won't know precisely what Iguodala has or hasn't embraced until the rest of the season is played. But what we do know is that something feels different around Iguodala.

"There's a thing called perception and there's a thing called reality," Collins said. "What we're trying to build here, he's the cornerstone of what we're building. . . . I just see in Dre, he feels we're heading in the right direction. I think he's starting to see some hope, things are changing, we're moving in the right direction."

This week. After the Nets game, the Sixers play at home against the New York Knicks on Friday, and at the Knicks on Sunday afternoon.
