tim duncan drops in rankings

For the first time since NBA.com has been conducting a preseason survey of the league’s general managers about the best of everything, Spurs captain Tim Duncan was not named the best of the league’s power forwards.

The GMs first were polled in 2002, after Duncan won his first Most Valuable Player award. He was an overwhelming choice as top power forward then and followed with seven more preseason designations as the league’s best.

This season, however, Dallas’ Dirk Nowitzki and the Lakers’ Pau Gasol tied as the top power forward, according to the GMs, each getting 28.6 percent of the vote. Duncan finished third, with 21.4 percent.

The GMs also picked Duncan the second-best center in the league, behind Orlando’s Dwight Howard.
