Dan Campbell critiques NFL's expanded challenge rule before Lions practice

Detroit Lions head coach Dan Campbell spoke about the NFL's new expanded challenge rule during practice on August 16, 2026. He recognized the rationale behind allowing assistant coaches to throw challenge flags but expressed skepticism about the responsibility that comes with it. Campbell stated he would not delegate this responsibility, as a failed challenge could lead to scrutiny directed at him rather than the assistant coach. He emphasized the absurdity of relinquishing such significant decision-making power. Campbell's current record with challenge calls is 10-14 since taking over his role in 2021.
