UPDATE: Kevin from Clipperblog's knee-jerk reaction by e-mail (he's about to blog about it):
Interesting. Do you think he's still a strong perimeter defender? If it gives Dunleavy the comfort of knowing that someone in the second unit can guard the wing and provide weak side help [Maggette can't really do either], assuming Livingston is on the ball, then it makes some sense. But I don't expect him to get too much playing time given how deep the Clips are there. I think more than anything, he's an insurance policy because Maggette is developing his traditional mid-season gimpiness.
