The Panthers actually have quite a bit of talent on offense, including, until he was traded, a top 5 running back. They have better receivers across the board than the Browns.

But it doesn't really matter. The only reason you want to shine a light on Stefanski isn't to really discredit him as a coach, it's to discredit him as a coach to prop up Mayfield. There is no propping up Mayfield. He's unproppable. You come across as a school kid with a crush who still has a Mayfield poster on his ceiling.
