It's not exactly "no comment," but essentially, that's the official stance in Memphis. Via SB Nation's Straight Outta Vancouver, we have the Grizzlies official response to today's "double-double" from Z-Bo:
“Since Zach Randolph became a member of this organization, he has been an active member of the Memphis community and embraced our core values of hard work and leadership. These qualities helped him develop into an NBA All-Star this season and guided one of the NBA’s youngest teams to a 16-game improvement.
“Zach’s continued commitment to the team has been evident the last couple of weeks as he’s been working out with members of our staff on the West Coast.
“Due to the ongoing police investigation, we do not feel it would be appropriate to comment further. Unless some other information surfaces, Zach remains a valued member of the Grizzlies family and Memphis community.”
