Dec. 20 -- Balloting for NBA All-Star 2006 is under way. To give you a better idea of the top voting options, NBA.com breaks down all six positions -- West guards, forwards and centers, and East guards, forwards and centers.

Today's Ballot Breakdown covers the centers for both the Western and Eastern Conferences, ranked statistically (by the sum total of their scoring, rebounding and assist averages). Read about Shaq, Yao and the other big men controlling the paint, then cast your vote and help select the starters for the 2006 All-Star Game in Houston on Feb. 19. (Note: All statistics are through games played on Dec. 19.)

Marcus Camby, Denver
Averages: 16.8 PPG, 13.3 RPG, 1.5 APG
Breakdown: If we had told you only a few short years ago that Camby would be putting up 16.8 points and a league-leading 13.3 boards -- both career highs -- you'd have called us crazy. Camby himself might have called us crazy. Even crazier: He ranks second in the league in blocks per game (3.19 bpg) and is averaging 1.43 steals a night.

Yao Ming, Houston
Averages: 19.9 PPG, 9.0 RPG, 1.3 APG
Breakdown: After one round of returns in All-Star balloting, Yao again leads the way collecting 729,178 votes thus far; last year he received a record 2,558,278 votes overall. This season he's averaging career highs in points and rebounds, but has been shelved for an indetermined time because of an injury to his left big toe.

Mehmet Okur, Utah
Averages: 17.9 PPG, 8.7 RPG, 2.0 APG
Breakdown: For a second year, Okur seems to be the only Jazz player able to avoid the injury bug as he's the only player to start every game this season for Jerry Sloan. The fifth-year center leads Utah in points and rebounds per game and paces the team in three-point field goal percentage (.383).

Brad Miller, Sacramento
Averages: 13.4 PPG, 7.7 RPG, 6.1 APG
Breakdown: Okay, so Brad Miller's scoring and rebounding averages are a tick down from recent seasons, but his assists average is through the roof. The seven-footer is averaging a team-best 6.1 dimes a game -- from the CENTER position.

Shaquille O'Neal, Miami
Averages: 16.3 PPG, 7.9 RPG, 1.6 APG
Breakdown: Shaq may have been sidelined for the first month of the season, but that didn't stop fans from casting votes for the Diesel -- he leads all Eastern Conference centers with 646,085 votes through first returns. His return to the court -- combined with Pat Riley's to the bench -- led to four straight Heat wins.

Zydrunas Ilgauskas, Cleveland
Averages: 14.9 PPG, 7.2 RPG, 0.9 APG
Breakdown: Ilgauskas, a two-time All-Star (2003, 2005), mans the middle for a revamped, if struggling, Cavaliers squad. While many of his numbers are down a bit from a year ago, his percentages are up significantly.

Wallace holds his own among taller and heavier opponents at the pivot.

Ben Wallace, Detroit
Averages: 8.6 PPG, 11.7 RPG, 1.9 APG
Breakdown: Wallace, a three-time All-Star (2003, 2004, 2005), could be headed to Houston in February. He's tallied the second-most votes (336,518) at the center position in the Eastern Conference and ranks in the top 15 in the league for rebounds, blocks and steals per game.

Nenad Krstic, New Jersey
Averages: 13.1 PPG, 5.7 RPG, 1.3 APG
Breakdown: Second-year center Krstic may not garner an All-Star nod this season, but his future looks bright. The Nets big man has improved on solid numbers posted during his rookie campaign and ranks among the sophomore leaders in many statistical categories.

Jamaal Magloire, MIL
Averages: 9.1 PPG, 10.3 RPG, 0.6 APG
Breakdown: Magloire is one of the big reasons the Bucks have rebounded from a 30-52 season last year. Coming to the Bucks in a trade in early October for Desmond Mason, Magloire is averaging near career highs in rebounding -- ranking third overall in offensive boards per game -- and blocks.

Kurt Thomas, Phoenix
Averages: 9.3 PPG, 9.0 RPG, 1.0 APG
Breakdown: Playing in a new uptempo system in Phoenix this year, Thomas struggled a little during the opening month. Through the month of December, however, he's found his groove, averaging 11.3 points, on .505 shooting, and 11.8 boards a game.

Others on the ballot: Eddy Curry, New York; Samuel Dalembert, Philadelphia; Andrew Bogut, Milwaukee; Chris Kaman, LA Clippers; Chris Mihm, LA Lakers; Brendan Haywood, Washington; Primoz Brezec, Charlotte; Joel Przybilla, Portland; Raef LaFrentz, Boston; Erick Dampier, Dallas; Michael Olowokandi, Minnesota; Lorenzen Wright, Memphis; Jeff Foster, Indiana; Jerome James, New York
