College football is back, and the rule book is (a little) different.

Although 2019 was classified as an off-year for rule changes, officials could still make edits if they involved player safety; adjustments to any recent change that was “not achieving its intent”; or if they would have “a significant impact on the image of the game.”

Here are a few of the revisions that will be in effect for this season.

There will be no gray area for targeting.

Past targeting calls were subject to video review with three possible outcomes: A call could be confirmed or overturned, or, if there wasn’t enough evidence to overturn it on the field, it could stand. The new rule no longer allows referees to “stand” with the play as called, meaning targeting penalties will be imposed only when they clearly withstand more scrutiny.

That new standard will apply only to targeting, not other kinds of plays. Turnovers and scoring plays, for example, will still stand if video evidence is not conclusive enough to overturn the original call.
