You don't want a better defensive team? The fact is, there are teams that have proven to be effective without a Ben Wallace type in the middle. And regardless of whether or not they are ideal to you, the fact is that they were BETTER than the kings, and were playoff teams that proved to be capable on the defensive end.
If I could trade with either team, sure, but ideally, you want to have a shot blocker. Doesn't have to be a Ben Wallace-like, all defense, no offense shot blocker. But at least someone who is a deterrent, who is going to contest at the rim and clean the defensive glass. I'm not a huge Dalembert fan, but we've NEVER had a guy with his shotblocking prowess. He's the kind of player we were looking for from 2000-2004 and could never quite get our hands on. He's certainly overpaid, but on his merits, he can add a lot to a team that's looking to win a championship. His value to us is certainly less than it would be to a contender, but there's nothing wrong with having him in the lineup.
