The San Antonio Spurs yesterday agreed to trade backup center Dave Corzine and starting forward Mark Olberding to the Chicago Bulls for veteran center Artis Gilmore.

The future of Corzine, who broke into the NBA with the Washington Bullets, had been in limbo since he announced a week ago that he had signed an offer sheet with the New Jersey Nets. It had been reported that the proposed contract was for $3.25 million over five years.

The Spurs had 15 days to match the Nets' offer or let Corzine, who became a free agent at the end of last season, go to New Jersey. The Spurs said they will match the offer, then deal Corzine and Olberding to Chicago for Gilmore.

Corzine, 6 feet 11 and 265 pounds, averaged 10.1 points and 7.7 rebounds last season. In the playoffs, he averaged 13.6 points and 9.4 rebounds.

Olberding, 6-9 and 230 pounds, averaged 13.8 points and 6.5 rebounds last season.

Gilmore, 32, has been an all-star nine of his 11 professional years.

"I don't see myself taking Artis' place," said Corzine, who was traded by Washington to San Antonio in September 1980 for two second-round draft picks. "I'm not the same type of player. I plan to play my game and help the Bulls. I'm a strong, smart player" . . .

The Bullets are close to signing forward Steve Lingenfelter, out of South Dakota State, who played in Italy last season.
