I've been one of the most vocal Anti-BBD people in the past, but I think he's done some decent things upon his return. However, I think my overall "beef" is with many posters here. I get sick of hearing how incredible a player BBD is and how he is the future of the Celtics starting rotation (or how he was going to turn this team around upon his return). Once you view him as a backup player who comes in for 8 to 10 reliable minutes on a championship team, then you appreciate what he does.
He's improved his rebounding, but that's it. And I'm happy about that. But he is most definitely looking out of shape, which there's no excuse for if you hurt your hand. His defensive rotations have always been subar and slow, which I've tried to point out and no-one listened, but it really does hurt the team. Overall he makes easy things look difficult (much like when Scally would dive for a ball that any normal player would run over and pick up with ease), and unless he gets some "ups" in his legs he won't be finishing around the hoop anytime soon. I do think he's improved his body control though, so that's good.
Overall I'm glad he's on this team b/c I think the Celtics need that depth and he hustles on the court, but in the playoffs I don't want to see him more than 8 minutes a game.
