In all, Oden appeared in just 82 career games for the Blazers, averaging 9.4 points and 7.3 rebounds
His knee problems drew comparisons to Sam Bowie, the injury-plagued center the Blazers took ahead of Michael Jordan in 1984. Bowie played in 76 games as a rookie but appeared in just 63 games over the next four seasons because of injuries.
Oden took this season off to rehab but has had interest from several teams for next season, including the Cleveland Cavaliers. Earlier this month, he went to see the Grizzlies play the Cavs in Ohio.
Mike Conley's father is Oden's agent.
"It was unbelievable to see him," the younger Conley said after the Grizzlies beat the Blazers 94-76. "I had dinner with him last night and I'll probably eat with him tonight, too. Just to see him in good spirits, he's always been a supporter of mine and I've always been a supporter of his.
"I'm just hoping that everything turns around for him and he's ready to go next year."
