24- Josef Nurkic: Nurkic is playing a lot worse then how he used to play. He has been injured, so he hasn't played many games and isn't playing many minutes. When he has played, he has been good but not good enough. He is averaging 9 points on bad-ok efficiency, but averaging 7.5 rebounds which is very good. Last year, he averaged over 17 points, with 10 rebounds and 4 assist. He is still passing the ball well, (3 assist) but this season his scoring numbers have dramatically went down. He still gets the 24 spot because he is a good rebounder, passer and defender.

23- Al Horford

The reason why Al Horford is so low is that he has played in under 30 games! Although he hasn't played as of late, he is playing a lot better this season, averaging 14-6-3 and he is a very good defender. He is really having a better season, and is playing well.

22- Daniel Theis Daniel Theis in Boston was a center that was overrated by Celtic fans (he was a big fan favorite for some reason) but underrated by the league. Whenever he plays, he is always a positive. He does have a harder time guarding Embiid and Jokic because he is an undersized big, but is switchable, and can guard 1-5. One of the best defensive centers, and a good comparison is Myles Turner. Both aren't great rebounders, same with passing, both can hit a 3 if you let them, only difference is really defense. Theis is a good center, that can certainly start and the Bulls really made a great trade getting him.

21- Stevan Adams

Stevan Adams is a really good rebounding center, and not that bad of a defender either. He is averaging more rebounds then assist (9.1 rebounds) and 7.8 points. The reason why he is 21st is that he doesn't get many points, he isn't that good of a defender, not a all NBA defense consideration, but a really good rebounder. Rebounding is an inportent skill for a center, but by itself wont get you into the top 15.

20- Maxi Kleber

Kleber is a slightly better version of Daniel Theis. A very good defender, and a really good 3 point shooter. On just over 4 attempts, he is a 40 precent 3 point shooter. He is also very efficient, even though he is 45 precent from 2 point attempts.
