Who is the NBA's worst defender who plays a significant amount of time at center (doesn't have to be full time but must play it at times)?

Tougher to assess. Guys like Jalen Duren and Onyeka Okongwu probably have pretty bad metrics, but give them some decent support and I think they could be adequate. For a heavy minute centre who I do not think can be adequate anymore, Vucevic may be my answer. He could be a mild contributor in his prime, but now his main role is to occupy space — and he barely manages that.

Vooch. The Bulls would have 40-43 Wins by now if Brook Lopez or Jakob Poetl was on the roster instead of Vucevic.

Obvious contenders are John Collins, James Wiseman, Marvin Bagley, Jalen Duren, Eubanks, and Vuc. Hard to pick between those guys.

Marvin Bagley, Zach Collins, Jalen Duren... probably the guys from the worst teams deserve a shoutout this season. All on terrible teams with no D.
