Parks and Rec after Mark left.

I dont think that’s Mark related. That show took off second season when the ramped up Ron and Andy and the addition of Chris and Ben.

He wasn’t my favorite character but the show was on the way up before he left

another answer that idk if it’s technically in the spirit of the question but Coach leaving and Winston coming onto New Girl.
