It was a tongue-in-cheek remark. However, I don't think it would hurt to bring him in for a workout to see if he still has any game left. Even if he's only 50% the player he was in during his MVP season, he could help. He couldn't be any worse than DJ Augustin.
If nothing else, it would get a lot of the casual fan's and the media's attention. If I was the GM I'd do it for the press and ticket sales alone.
