I wouldn't say one of the worst, more like slightly below average. I don't know if they're still looking for another forward but I think Barnes really could've helped them (as others said Grant Hill would've been ideal).
Not really a big deal though, I'm sure Artest will at LEAST split his minutes between the bench and the starters. If he continues to decline, Meeks might even steal his spot in the rotation. That extra spacing is huge for their lineup, and the Lakers have been one of those teams that like a 3 guard lineup.
