As a King, his best games have been against Charlotte, San Antonio, New Orleans, Portland, and the Clippers. The Clippers are good. His worst games have been against Golden State, Milwaukee, Boston, and New York.
I didn't pay much attention to Zach pre Kings. It might not be an issue, or it might be a Sac issue more than a Zach issue.
I'll gladly give him kudos if he leads us out of the play in but I'm not yet convinced.
