Domantas Sabonis brings a lot to the Sacramento Kings. He's an elite scorer, not to mention the top rebounder in the NBA. That's three seasons running at this point. On top of that, Sabonis is one heck of a passer for a big man, though that's mostly a symptom of how many rebounds he gets.
The only real hole in his game is on defense. Admittedly, it's a pretty big gap for a team's center. When he's the primary defender, his lack of quickness on the closeout often opens up three-point shots for the opposition. His fundamentals are solid, but defensive effort is an issue, as is foul trouble.
