Duncan and Bowen highlight NBA All-Defensive team
Bowen, also a forward, received 42 votes, six more than Duncan.
Denver Nuggets center Marcus Camby, the Defensive Player of the Year, was chosen for the third time. Rounding out the first team were guards Kobe Bryant of the Los Angeles Lakers, who earned his seventh selection, and Raja Bell of the Phoenix Suns, making his first appearance on the team.
Bowen and Duncan helped the Spurs hold opponents to 90.1 points (first in the NBA). San Antonio has finished in the top five in the category in each of Duncan's 10 seasons.
Camby led the NBA in blocks per game (3.30) and was tied for fourth in rebounds (11.7). Bryant ranked 17th in steals (1.44), while Bell often matches up against the opposition's best offensive player.
The second team consists of Chicago teammates Ben Wallace and Kirk Hinrich, New Jersey's Jason Kidd, Detroit's Tayshaun Prince and Minnesota's Kevin Garnett.
Voting was done by the league's 30 head coaches, who were not allowed to vote for their own players.
