Rasheed Wallace helped transform the Detroit Pistons from contenders to NBA champions last month. Now, he's coming back for more.

The unrestricted free agent forward has agreed to a five-year contract worth $57 million, two sources told the Associated Press yesterday. One of the league sources, who spoke on the condition of anonymity, expected Wallace to sign the deal today. . . .

The New Orleans Hornets hired former NBA head coach Darrell Walker as an assistant, the team said. Walker, 43, a scout and former interim head coach for the Washington Wizards, will work under Hornets Coach Byron Scott, who was hired in May.

* COLLEGES: For the second straight year, the University of Maryland finished in the top 25 in the Directors' Cup standings, an annual ranking of athletic departments by the NCAA Directors of Athletics that weighs success in 20 sports.

Maryland was joined in the top 25 by fellow ACC schools North Carolina (seventh), Duke (18th) and Florida State (22nd).

* COLLEGE FOOTBALL: Eddie Robinson, college football's winningest coach, has Alzheimer's, his wife said.

"He's pretty bad," Doris Robinson said. "He gets a little bit worse every day. He comes to the table for breakfast, but after that he wants to go right to bed."

During his 57 years at Grambling, a career that spanned 11 presidents, several wars and the Civil Rights Movement, Robinson compiled a record of 408-165-15.

Robinson, 85, started showing signs of the disease soon after his retirement from Grambling after the 1997 season, his wife said.

British Open champion Todd Hamilton, wearing a "Royal Todd" T-shirt and a relaxed grin, was greeted at Dallas-Fort Worth International Airport near his home by about 20 golfing buddies and a stampede of camera crews.

"I hope this won't go to my head," Hamilton said. "I think these guys behind me won't let that happen."
