Mbah a Moute has been one my "does want" list since we lost Brucey. Here's why in Luc's own words from the ESPN article.
Also, here's a bit of my speculation on what he could do for the team. He can't give you a corner 3-ball, but we don't need it from him, plus we could help him get there. Defense, defense, defense. If we can pry him loose from the Bucks, maybe we eventually start him at the 3 and give Jefferson a "Manu-esque" roll off the bench (I know, comparing RJ and Manu may leave some feeling nauseous), allowing him to improve bench play.
