PHOENIX — Michael Beasley says his marijuana issues are a thing of the past and is ready to show the Phoenix Suns their support for him is warranted.

The 6-foot-10 forward, who became a free agent when Minnesota declined an $8 million option to keep him, signed a three-year, $18 million contract with Phoenix on Friday.

Beasley, 23, faced questions about his past at a news conference.

"I realize 10 minutes of feeling good is not really worth putting my life and my career and my legacy in jeopardy," he said, "so I'm confident to say that that part of my career, that part of my life, is over and won't be coming back."

In June 2011, Beasley was ticketed for possessing marijuana and speeding in a Minneapolis suburb. He also has acknowledged that while playing for Miami, he twice violated the league's drug policy and entered a treatment facility in 2009.

Beasley, a former Kansas State standout who was the second player drafted in 2008, credits working with former NBA player Norm Nixon for getting his priorities straight.

"I've really realized my potential," Beasley said. "I've really realized what I can do."

Suns general manager Lance Blanks was effusive in his praise of Beasley's honesty as well as the talent he brings to the rebuilding Phoenix organization.

"Regardless of his past and regardless of any thoughts that people may have, we are excited," Blanks said. "I know I am excited to embrace everything he is about and most importantly wants to be as a Phoenix Sun."

Celtics acquire Lee

The Houston Rockets will send guard Courtney Lee to the Boston Celtics as part of a multiteam, sign-and-trade deal.

The Rockets will get a second-round pick in next year's draft from Boston, forward JaJuan Johnson, guard E'Twaun Moore and forward/center Sean Williams.

Houston will also acquire the rights to guard Jon Diebler from Portland.

The Celtics completed the trade by sending guard/forward Sasha Pavlovic to Portland.

Lee, 26, reportedly has a four-year deal worth $21.5 million.

Notes

• Orlando center Dwight Howard is often mentioned in trade rumors. ESPN quoted Howard's agent, Dan Fegan, as saying his client intends to explore free agency next summer no matter which team trades for him.

• Guard Jason Kidd of the New York Knicks has apologized on Twitter for being charged with driving under the influence.

Kidd, 39, crashed his SUV into a telephone pole in the Hamptons on Sunday, Southampton Town police said. He was treated at a hospital for minor injuries.

Kidd wrote he regrets "any disruption my accident last weekend may have caused members of the community and want to thank the local authorities."

• Forward Jordan Hill, 24, is returning to the Los Angeles Lakers, according to a Twitter item from Kevin Bradbury, his agent.

• Portland forward Nicolas Batum, 23, signed a four-year offer sheet from Minnesota reportedly worth from $45 million to $46.5 million that was matched by the Trail Blazers on Wednesday.

Batum had said he wanted to play in Minnesota but told Oregon media he also is happy in Portland. "It was a tough choice, believe me," said Batum, who earned slightly more than $2 million last season.

• Ex-Washington Huskies guard Tony Wroten Jr., who was drafted in the first round last month, scored six points and had a game-high eight assists to help the Memphis Grizzlies beat the Charlotte Bobcats 97-79 in an NBA Summer League game in Las Vegas.

Wroten, a graduate of Garfield High School in Seattle, is shooting 37 percent from the field (10 of 27) for the Grizzlies (2-1).
