I think Vucevic would be a really good fit for the Lakers, he's far from what AD can offer defensively, but Vucevic is an offensively awesome center piece, he can score easily inside the paint and he's also got really great numbers from behind the arc as well.

Jakob Poeltl is also a good choice, but Steven Adams as it is now doesn't seem like a good first choice center to me, not because of his ability but that of his health concerns, I'm not sure Steven Adams can handle big minutes anymore let alone back to back games when the situation requires it, the Lakers might need whoever they have on their roster to be available for the final stretch of the season, if they're to make a run for a possible post season campaign.
