Aaron Rodgers will sit out the Steelers' 1st preseason game per Mike Tomlin, who says the decision isn’t injury-related but based on veteran experience

Rodgers is right. While there are some clear benefits to preseason football (like going against someone other than your teammates), there isn't a lot that can be gained if you're a player of Rodgers' caliber. As Rodgers stated, offenses aren't facing defenses that are game-planning against them, and vice versa.
