Nov. 23 -- Balloting for NBA All-Star 2005 is under way. To give you a better idea of the top voting options, NBA.com will break down all six positions -- West guards, forwards and centers, and East guards, forwards and centers -- over the coming weeks. Today's Ballot Breakdown covers the Western Conference centers, ranked statistically. Read about Yao, Miller and company, then cast your vote and help select the starting lineups for the 2005 All-Star Game in Denver on Feb. 17. (Note: All statistics are through games played on Nov. 22.)

Yao Ming, Rockets
Averages: 18.4 PPG, 8.0 RPG, 1.3 APG, 1.33 BPG
Breakdown: Yao's numbers certainly don't lie; he's one of the top big men in the game today. But his play has been erratic at times this season, and the Rockets are off to a somewhat disappointing 6-6 start. Also worth noting: In games where Yao scores 20 or more, the Rockets are just 1-4.

Yao and Miller are two of the top big men in the West.

Brad Miller, Kings
Averages: 15.5 PPG, 8.5 RPG, 2.6 APG, 1.10 BPG
Breakdown: After stumbling out of the gate, Miller and the Kings have rediscovered their winning ways and are currently riding a five-game winning streak. Miller might not be putting up the gaudy assist numbers he did last season, but his all-around skills from the center spot are still among the best in the game.

Jamaal Magloire, Hornets
Averages: 12.1 PPG, 8.5 RPG, 1.8 APG, 0.88 BPG
Breakdown: The Hornets have struggled mightily with their move to the West, but Magloire has been solid in the middle this season, although his shooting and rebounding have declined slightly from 2003-04.

Rasho Nesterovic, Spurs
Averages: 8.2 PPG, 7.4 RPG, 1.5 APG, 1.60 BPG
Breakdown: Nesterovic has been as steady as ever this season in helping the Spurs hold on to first place in the Southwest Division.

Erick Dampier, Mavericks
Averages: 8.5 PPG, 7.0 RPG, 1.1 APG, 1.00 BPG
Breakdown: While Dampier isn't matching his gaudy numbers from last season in Golden State, he's doing what the Mavs need him to in the post. And perhaps most importantly, he's helping them win.

Wright (L) and Dampier have also emerged as strong ballot options in the West.

Marcus Camby, Nuggets
Averages: 5.9 PPG, 7.3 RPG, 1.0 APG, 2.25 BPG
Breakdown: Camby's numbers are down from last season, but he's helped the Nuggets right their season after a slow start.

Lorenzen Wright, Grizzlies
Averages: 5.8 PPG, 7.1 RPG, 1.7 APG, 0.67 BPG
Breakdown: Wright has been as solid as ever defensively, but his shooting (.333 field-goal percentage) is way down from his career .455 mark.

Theo Ratliff, Blazers
Averages: 4.2 PPG, 5.1 RPG, 0.3 APG, 3.00 BPG
Breakdown: While Ratliff's numbers are down from last season, he's still making a big impact for the Blazers defensively. In fact, with Shaq in Miami, Theo might be the most intimidating low-post defender in the conference.

Others:
Vlade Divac, Lakers: Divac has yet to play this season due to a back injury, but expects to play very soon.
Brian Grant, Lakers: Grant's numbers this season have taken a slight hit (4.5 PPG, 3.3 RPG) due to Chris Mihm's emergence.
Chris Kaman, Clippers: Kaman is expected to rejoin the team soon after missing time due to an injured ankle. He has yet to play this season.
Chris Mihm, Lakers: Averaging career-highs in points (11.9) and rebounds (6.6), Mihm is a strong candidate for write-in consideration.
Mehmet Okur, Jazz: Okur's solid numbers (9.3 PPG, 6.1 RPG) also warrant write-in consideration.
Dikembe Mutombo, Rockets: Deke has been solid in spot duty backing up Yao (4.0 PPG, 4.0 RPG, 1.64 BPG) although he has yet to tally his first assist this season.
Chris Wilcox, Clippers: Wilcox, who normally plays power forward, was forced into center duty due to Kaman's injury. He's responded with 15.5 PPG and 7.5 RPG, meaning, like Mihm and Okur, he's a worthy write-in candidate.
