BIGGEST NEEDS: The Mavs needed an infusion of youth and athleticism, especially on the perimeter. They signed Gerald Green and re-signed Antoine Wright to shore up the swing spots. Reyshawn Terry and Foster also have a shot to make the roster. Another veteran backup point guard might be a target.

FREE AGENT FOCUS: Antoine Wright, Gana Diop, Gerald Green, J.J. Barea and James Singleton have signed contracts. Keith McLeod also inked a non-guaranteed deal. Other than another minor move, the team is basically done in the free-agent market.

PLAYER NOTES:

--F James Singleton signed for one year at the league minimum. He played last season in Spain and the two previous years were spent with the Los Angeles Clippers. He has career averages of 2.6 points, 2.7 rebounds and 10.1 minutes in 112 career games. He sold the Mavs on his hustle and versatility, especially on the defensive end.

"I do the little things," Singleton said. "If you need an extra possession or you need to guard a bigger three or a more agile four or if you need a guy to switch on a point guard on a pick-and-roll, I can do it. In the West, we have some great guards in Chris Paul, Steve Nash, Kobe Bryant. I'm able to switch out on those guys and give the team versatility in different areas."

--G Antoine Wright re-upped for two years and about $4 million. He spent half of last season with the Mavs after being traded from New Jersey as part of the Jason Kidd blockbuster. The former first-round pick out of Texas A&M joins the swingman rotation that also includes Josh Howard, Gerald Green and Jerry Stackhouse.

"We are excited that Antoine will be returning to Dallas next season," president of basketball operations Donnie Nelson said. "He is an emerging young prospect with tremendous promise. With his youth, athleticism and talent, he has a very bright future in Dallas."

--G Keith McLeod signed a non-guaranteed contract that includes a training camp invite. McLeod played for Carlisle two years ago in Indiana and joins J.J. Barea as true backup point guards behind Kidd.

The four-year pro (6-2, 190) has played with four NBA teams, and holds career averages of 5.5 points, 2.7 assists and 1.3 rebounds in 200 games with 88 starts.

"Right now, I'm just taking it day by day and trying to better myself and help the team," McLeod said. "Hopefully, that will lead me into training camp and open other opportunities for me."

--G Renaldas Seibutis left the summer league team after its stint in Las Vegas to return to Europe. It became obvious that the 2007 second-round pick wouldn't stick with the big club this fall, so the promising guard headed back overseas for more seasoning. He could also stand to pack on a few more pounds of muscle. The Mavs continue to hold his NBA rights.
