Greg Oden to participate in Mavericks' free-agent minicamp

DALLAS -- Former No. 1 overall pick Greg Oden will participate in the Dallas Mavericks' free-agent minicamp next week as he continues to work toward another NBA comeback, a source said.

Oden, the 7-footer selected by the Portland Trail Blazers over Kevin Durant in the 2007 draft, has been limited to 105 games due to multiple microfracture knee surgeries and other issues. He last played for the Miami Heat in 2013-14, appearing in 23 games after a three-season layoff.

Ohio State coach Thad Matta, who coached Oden during his one season in college, told reporters at the NCAA tournament in Portland that Oden had been doing "high-level training" on campus for sixth months and had slimmed down to about 280 pounds.

"Quite honestly, I haven't seen Greg look this good since when he played for us back in the day at Ohio State," Matta said in March. "His attitude is off the charts."

The Mavs attempted to sign Oden for the veteran's minimum in the summer of 2013. He later said his decision came down to Miami or Dallas.

"It's just a good organization," Oden said of the Mavs when the Heat came to Dallas that season. "I know the training staff and I know they're really good. Their track record shows it. That was the main thing."
