http://sports.espn.go.com/nba/news/story?id=1837273 ESPN.com Unrestricted free agent guard Brent Barry will sign a four-year deal with the San Antonio Spurs for between $22 and $24 million, a source told ESPN's David Aldridge. The 32-year-old Barry chose the Spurs over a four-year offer for the full mid-level exception from the Portland Trail Blazers, in part because he thought the Spurs were closer to contending for a championship. Barry also turned down a three-year offer worth $18 million from his former team, the Seattle Sonics, wanting a four-year offer. Barry's signing completes a strong 48-hour period for the Spurs; they agreed to terms on Thursday with guard Manu Ginobili. The Spurs will now have a three-guard rotation of Tony Parker, Ginobili and Barry, who can play both guard positions. The Spurs are now expected to complete their offseason spending by re-signing forward Bruce Bowen, who opted out of the last year of his contract. Bowen is expected to receive a three-year deal from San Antonio worth $9 million. Now that the Sonics have lost Barry, discussions they were having with the Rockets about trading guard Antonio Daniels for draft picks probably will end as well.
