DALLAS – The way Jerry Stackhouse's contract was structured, the Dallas Mavericks knew they could parlay him into a key player for next season. As it turned out, several teams benefited.

Dallas, Toronto, Memphis and Orlando combined in a massive swap Thursday that included eight players, a draft pick and stacks of cash. The deal sent Shawn Marion in a sign-and-trade from Toronto to Dallas and Stackhouse to Memphis and helped seal the transaction that moved Hedo Turkoglu from Orlando to Toronto.

Among the other pieces: Kris Humphries, Nathan Jawai and cash went from Toronto to Dallas; Greg Buckner went from Memphis to Dallas; and Antoine Wright and Devean George went from Dallas to Toronto.

Memphis also received a second-round pick and cash from Toronto and cash from Dallas. The Mavericks and Raptors also sent cash to Orlando.

The Magic was going to lose Turkoglu anyway. After Orlando acquired Vince Carter, Turkoglu opted out of his contract and became a free agent. He'd already decided to go to Toronto, but turning his departure into a sign-and-trade glued together the rest of this complex puzzle.

"So many things were going on that I was like, 'Just sit back and wait until it happens,' " Marion said. "I'm just happy to come to Dallas."

The Mavericks hope Marion, a four-time All-Star nicknamed "The Matrix" for his do-it-all game, will be a great complement to a starting lineup featuring Dirk Nowitzki, Jason Kidd and Josh Howard.

Although Howard and Marion have similar skills, Marion said, "I think we can mesh fine. I'm a basketball player. I've played a little bit of every (position) before."

Marion was a matchup nightmare during his heyday with Phoenix – too big for Howard, too quick for Nowitzki. His career averages are 17.8 points, 9.9 rebounds, 2.0 assists, 1.83 steals and 1.31 blocks.

Yet Marion is also 31 and headed to his fourth team since February 2008, having bounced from Phoenix to Miami to Toronto. He's also coming off a season in which he had his fewest points, rebounds, blocks and steals since his rookie season.

But this change is different. He's arriving before the season and on a team with legitimate hopes for a deep playoff run. He also has the security of a new five-year, $39 million contract from the sign-and-trade.

"At the end of the day, everybody wants security," Marion said. "If you can get security and get a great home at the same time, why not?"

Stackhouse was enticing for his numbers – contractually, that is. Although Stackhouse is due more than $7 million next season, he can be bought out for only $2 million. That's likely the amount of cash Memphis received for the 34-year-old swingman. The former scoring star played only 10 games last season because of injuries but soon will be able to cut a deal with any team.

Raptors – A pitch from Chris Bosh helped Toronto land Turkoglu, who was already considering Toronto because he liked the city.

"When I heard his voice, I was really happy about it," said Turkoglu, who received a five-year deal reportedly worth about $53 million. "He's been an All-Star in this league, and he's been a dominant player. I was just happy to hear I'm welcome by that type of guy."

Trail Blazers – After losing out on Turkoglu, Portland is considering restricted free agent Paul Millsap from Utah, general manager Kevin Pritchard said.

Cavaliers – Free agent Anderson Varejao agreed to a multiyear contract to stay with Cleveland. Agent Dan Fegan told the Cleveland Plain Dealer that Varejao agreed to a six-year deal worth up to $50 million.

Pistons – Detroit introduced Cleveland assistant John Kuester as its sixth head coach in 10 years. Kuester, an assistant for 13 years with five teams who never has been an NBA head coach, signed a three-year deal.

Clippers – Los Angeles signed No. 1 overall draft pick Blake Griffin.
