As things sit currently, the Packers would need to utilize a targeted approach to play ball control on offense. Do what's necessary to limit the possessions of Mahomes.
And when the Chiefs do get the ball (and I know some will scoff at this), we need to play bend but don't break defense. Give them the underneath stuff. Make them nickel and dime it down the field. The more plays you force them to run, the more likely they could make a mistake.
Not only that, you don't let them beat you over the top. As long as you don't let them beat you over the top, you get them in the redzone where the field shrinks. All of a sudden, there's not near as much room for someone like Tyreek Hill to use his best asset. And for Mahomes to use his.
I haven't fact checked this, but I've heard it multiple times, and I've observed it a little. The Chiefs aren't a very good redzone team. I believe they rank in the bottom third.
Make the Chiefs kick for 3, and rely on Rodgers to get you 7. That's the formula.
