Corliss Williamson is set to retire from the NBA and become an assistant coach at Arkansas Baptist College, the school's athletic director said Tuesday.

Williamson, who led Arkansas to the 1994 national championship, has played 12 pro seasons with Sacramento, Toronto, Detroit and Philadelphia. He was on the Pistons when they won the 2004 NBA title.

Williamson averaged 9.1 points in 68 games last season with Sacramento.

According to a league source, a trade was discussed this summer that would have sent Mike Bibby to Miami and brought Jason Williams back to Sacramento.

Williams and forward Udonis Haslem were offered in return, and possibly draft picks. Additionally, Miami was seriously interested in Artest, but the Kings didn't appear eager to move the small forward.

The consensus seems to be that -- barring an offer they can't refuse -- the Kings want to see Artest in action this season and feel somewhat confident he will both produce and avoid the off-court controversy that marred last season.

Charley Walters of the Pioneer Press expects to see Timberwolves assistant Rex Kalamian, who was hired by departed coach Dwane Casey, to leave this week to join the Sacramento Kings under new coach Reggie Theus.

The NBA has settled on Cal Expo as the preferred location for a new Kings arena, according to sources familiar with the league's behind-the-scenes effort to build the team a new home in Sacramento.

Despite its location on one of Sacramento's worst freeway bottlenecks, Cal Expo appeals to the NBA because it offers a ready supply of vacant land and a name already recognized as an entertainment destination, said the sources, who asked not to be identified because the league hasn't yet unveiled its proposal.

NBA Commissioner David Stern has said he will reveal his plan for a new arena about the time the basketball season starts this fall. League consultant John Moag, who is in charge of the effort, said he will come to Sacramento later this month to brief elected officials on his progress.
