Domantas Sabonis is arguably one of the best big men in the NBA today. His rebounding is number one in the league in addition to him being one of the top passers around at his size. Add into that his scoring, and you've got one heck of a five.
There are two problems that plague Sabonis, unfortunately. One of them is something he can control while the other is on the Kings. The issue that's on Domantas is his defensive presence. At his size and skill, he should be an elite rim protector. He's not, and it's something he needs to do better at.
