Per club policy, terms of the contract were not announced.
"I look forward to joining a franchise I'm very familiar with," said Powell.
"The Hawks have done some great things over the past few years, and I think
it's great to come back home and play here. They've enjoyed success in the
East, and while they have room to improve and grow, the nucleus is here to
make that next step."
The 6-foot-9, 240-pound Powell spent the last two seasons with the Lakers and
served as a backup for both championship teams. He contributed 2.7 points and
1.8 rebounds per game in 63 regular season contests last season in Los
Angeles. Powell also saw action in 13 playoff games in 2010, but averaged a
mere 0.7 points and 0.5 boards.
Powell, 27, played his high school ball at Riverdale in Georgia before playing
collegiately at North Carolina State, but left after his sophomore year. After
going undrafted in the 2003 NBA Draft, Powell decided to go play in Europe,
then was signed by the Dallas Mavericks in 2005.
Over 261 career games -- 28 starts -- Powell has compiled per game averages of
3.8 points and 3.0 rebounds with the Mavericks, Indiana, Golden State, Los Angeles Clippers and Lakers.
NCAA Football Betting : USC's reward: Top spot in Top 25
NEW YORK (AP) -By staying away from the cupcakes, Southern California earned itself a slim new ranking.
No. 1 always seems to fit USC.
Southern California jumped two spots to No. 1 in The Associated Press Top 25 on Tuesday, rewarded by voters for opening the season with a dominant performance on the road against a BCS conference opponent.
Georgia and Ohio State, the preseason Nos. 1 and 2, respectively, started their seasons with glorified scrimmages at home against FCS (formerly I-AA) teams. USC, however, traveled across country to face Virginia and could not have been more impressive in a 52-7 victory.
Georgia fell to No. 2 and Ohio State to No 3.
"We realize that rankings so early in a season are certainly fluid. But rankings do help establish a pecking order for things later in the season," USC coach Pete Carroll said in a statement. "As for moving into the No. 1 spot, it's nice to know that people think highly of our team."
Since reaching No. 1 on Dec. 7, 2003, the final-regular season AP poll of that season, USC has been No. 1 in 39 polls, by far the most of any team during that time.
"Some have said the voters are taking our schedule into consideration," Carroll said. "Our philosophy has always been to schedule outstanding opponents. We need to play challenging games like we just did, traveling across the country to open the season at Virginia. Games like that bring out our best and make us stronger as a team."
The latest voting was close. USC received 21 first-place votes and 1,539 points from the 65-member media panel. Georgia had 20 first-place votes and 1,506 points. Ohio State got 15 first-place votes and 1,497 points.
"I'd say we've evolved as pollsters," said Stewart Mandel of SI.com, who moved USC up to No. 1. "In the past, voters just kind of automatically moved teams up and kept teams where they were if they won."
Georgia beat Georgia Southern 45-21 on Saturday and Ohio State opened with a 43-0 win over Youngstown State.
"There's a bit of a growing backlash for the amount of teams that open with I-AA cupcakes," said Mandel, whose book "Bowls, Polls and Tattered Souls" chronicles college football's controversies. "To see a team [USC] go on the road and play a New Year's Day bowl team from last season, and not only play them but destroy them, how could you not reward that team?"
USC also jumped past Georgia to No. 1 in the USA Today coaches' poll, which has the same top five as the AP poll.
"It's definitely a privilege to be No. 1. But it's not heartbreaking to me if we drop," Georgia offensive lineman Josh Davis said. "It doesn't matter right now what we're ranked. What matters is our next game and right now, that's Central Michigan. The only time the polls matter is in December. That's when the polls matter."
While the Bulldogs opened easy, their schedule ultimately should be as difficult as any team's. Georgia's big nonconference test is at No. 15 Arizona State on Sept. 20. The Bulldogs also face six Southeastern Conference rivals that've been ranked in the first two polls.
As for Ohio State, the Buckeyes play at USC on Sept. 13 before getting into the Big Ten schedule.
But of the teams in this week's top 10, USC and Texas are the only ones that don't play an FCS opponent, and the Trojans are the only team that doesn't play a team from a non-BCS conference.

The last team to drop from No. 1 after a victory was USC last season. LSU jumped from No. 2 to No. 1 when it beat Tulane 34-9, the same week the Trojans edged Washington 27-24 on the road.
The last preseason No. 1 team to lose the top spot after winning its opening game was Florida in 2001. The Gators beat Marshall 49-14, but preseason No. 2 Miami opened with a 33-7 victory over Penn State and the Hurricanes jumped to No. 1 with Florida slipping to second.
The next four teams in the new Top 25 stayed the same: No. 4 Oklahoma (two first-place votes), No. 5 Florida (five first-place votes), No. 6 Missouri (one first-place vote), No. 7 LSU (one first-place vote) and No. 8 West Virginia.
No. 9 Auburn and No. 10 Texas each moved up a spot, taking advantage of Clemson's big drop. Clemson, ninth in the preseason, fell out after losing 34-10 to Alabama on Saturday.
Also falling out after losses were Virginia Tech, Pittsburgh and Tennessee.
Moving into the rankings were No. 21 Fresno State, No. 22 Utah, No. 23 UCLA and No. 24 South Carolina.
Alabama moved up 11 spots after its big victory over Clemson.
The second 10 started with No. 11 Wisconsin, followed by Texas Tech, Alabama and Kansas. BYU and Arizona State were tied for 15th. Rivals BYU and Utah are both ranked for the first time since 1996.
South Florida was No. 17, ahead of Oregon, Penn State and Wake Forest at No. 20.
The final five were all the teams to move into the ranking, except for Illinois, which dropped four spots and tied South Carolina for No. 24.
