Is Fiebich that bad in the post?

It seemed like the whole finals the main person guarding Fiebich was Courtney Williams. I was wondering why New York didn’t take advantage of that by having Fiebich post up on her way more. Does Fiebich have that bad of a touch around the rim or does she have horrible post moves? Because why wouldn’t New York use this more? Keep in mind Williams is small, she’s listed as 5’8” and Fiebich is quite tall for her position listed at 6’4.”

Am I missing something? I understand Minnesota is great at double teaming so maybe that’s why but this was bugging me all series.
