The NFL really seems to like making at least one fairly significant rule change during the offseason. This year, the biggest change concerned the pass interference penalty, because now, for at least a one-year trial basis, penalties—whether on the offense or defense, and whether called on the field or not—are going to be challengeable.
It is the first step in what may turn out to be a forward push to introduce more penalties calls to the replay system, something that multiple members of the Competition Committee talked about in recent months when the original rule was passed.
But it’s already been tweaked since then, making the rule an exception in yet another way.
