Danny Ainge is open to trade offers for his fifth overall pick in June's draft.

Trade talks already have taken place, and more scenarios figure to be explored as the week goes on.

?So many calls are made for financial reasons,? Ainge said. ?The trade world is just so different than any fan has any comprehension about. A lot of teams want to make deals that either free up money or cut their payroll just for cap or luxury tax reasons.?

Greg Oden has been drafted by a trading card company, and will be on the same team as Bill Russell.

Oden, a possible No. 1 draft pick after leaving Ohio State following his freshman year, signed a three-year contract worth at least $3 million Tuesday to become a spokesman for Topps Co. His first deal? A card featuring him and Russell, the Boston Celtics Hall of Famer, on the 50th anniversary of the company's first basketball set.

Like Russell, Oden is known for his ability to dominate a game on the defensive end with his rebounding and shot blocking.

"Certainly there's been a lot of comparisons to Bill Russell, which we don't run away from," said Bill Sanders, a vice president for BDA Sports Management, which represents Oden.

"I think that Greg has got a lot of that in him, but he's also got other skills in him that people don't necessarily associate with Bill Russell. Certainly he's honored to be mentioned in that kind of company. I think one of his goals is to accomplish a little bit of what Bill Russell did."

Greg Oden signed a multiyear deal Tuesday to become a spokesman for Topps Co.

A card featuring him and Bill Russell, the Boston Celtics Hall of Famer, on the 50th anniversary of the company's first basketball set will be his first feature.

"Certainly there's been a lot of comparisons to Bill Russell, which we don't run away from,'' said Bill Sanders, a vice president for BDA Sports Management, which represents Oden.

Marvin Barnes was arrested early Tuesday and charged with cocaine possession, the latest legal problem for the former basketball star who has been battling drug addiction for years.

Police said they found a bag of cocaine inside an SUV that the 54-year-old Barnes was driving.

Barnes, nicknamed "Bad News" for his off-the-court problems, was arrested along a highway shoulder in Johnston, said Major Steven O'Donnell, a state police spokesman.

The Boston Celtics announced today that they have extended the contract of Head Coach Glenn ?Doc? Rivers. Per team policy, terms of the deal were not disclosed.

?Doc is a leader and I have all the confidence in the world in Doc as coach of the Celtics.  With Doc as our coach we have the continuity that is crucial in the development of the franchise.? Danny Ainge said, Celtics Executive Director of Basketball Operations.

Rivers just completed his third season with the Celtics and has amassed a record of 102-144.  Rivers earned his first coaching win with the Celtics on November 6, 2004 against the New York Knicks in Madison Square Garden with a 107-73 victory. Rivers recorded his 100th Celtics coaching win against the Orlando Magic on March 28, 2007 in a 105-96 double-overtime victory.

In his first season with the Celtics, Rivers led the Celtics to their first Atlantic Division title since the 1991-92 season.  During the 2005 Playoffs under Rivers, the Celtics battled with the Indiana Pacers but were ultimately defeated in the seventh game of the first round.

?I am happy to be the Head Coach of the Boston Celtics. Moving forward I am more determined to move this franchise in the right direction and I believe that I can do that.? Rivers said.

Paul Pierce had lobbied hard to make the USA Basketball team, but he can't seem to convince his body to follow his heart.

Jerry Colangelo, the managing director of the men's team who has been putting together the squad, told reporters on Tuesday that the Celtics star will not be on the team that will compete in qualifying this summer.

"By not playing this summer, he is pretty much eliminated from playing in the Olympics," Colangelo said, according to the Boston Globe. "It would be hard to make the case that you should play in the third year after missing the first two. He understands that."
