The San Antonio Spurs are one of the teams that Portland free agent Joel Pryzbilla is considering, according to his agent Bill Duffy.

"He's wide open," Duffy said. "Nothing has been looked at too closely yet, but he certainly has a lot of respect for the Spurs."

The Spurs are limited to offering Przybilla their midlevel exception, expected to be worth about $5 million. They can extend the contract to as many as five years for a total of around $29 million.

Chicago, who have cap room, will likely establish the market for centers. The Bulls reportedly are first targeting Detroit's Ben Wallace. If Chicago does not sign him, Przybilla could be among the Bulls' other options.

In addition to being able to offer Przybilla a substantially larger contract than either Portland or the Spurs, Chicago also is close to Przybilla's home in Milwaukee. Duffy said it's "too soon" to tell whether the Spurs' financial limitations would hurt them.

Przybilla has said he would like to play for a winning team, but he also hasn't ruled out returning to Portland.
