If Bynum keeps playing like this, the Lakers won't bother trading for Dwight.
I wouldn't be surprised if they didn't trade for Dwight, anyway, since they don't want to give up both Pau and Bynum and that's going to be the asking price, most likely.
Still, Bynum is a very good center; 2nd best in the league when he's healthy. But I think he benefits a ton from the players he's got around him. I'm not sure how successful he'd be if he were the focus of the opposing team's gameplan every night. Also, he seems to be fairly inconsistent. Plus there's the injury issues and the attitude . . . but yeah, he's real good.
In short, his debut game performance isn't all that surprising -- especially coming against the Nuggets, who don't exactly have a great defensive front-court. I like Nene covering power forwards a lot more than true centers like Bynum. Luckily for Nene, there are really only 2-3 players with Bynum's physical profile in the entire league (Bynum, Bogut, Howard, and to a lesser extent Brook Lopez).
