The NFL has issued a clarification on its much-debated roughing the passer rule after three weeks of outrage from players, coaches and fans. The anticipated result, according to executive vice president Troy Vincent, is to "ensure consistency in officiating the rule."

Referees have thrown 34 flags for roughing the passer this season, more than twice the total over the same period in 2017, in part due to a point of emphasis against defenders landing on quarterbacks with all or most of their body weight. Officials have interpreted that point of emphasis in noticeably different ways, at times resulting in penalties for hits that appeared all but impossible for defenders to avoid.

In a statement, Vincent announced that the NFL competition committee had sent a video to teams that would clarify legal and illegal hits against the quarterback. The video, also released publicly, showed four examples of hits that will still draw a foul -- including one that broke the collarbone of Green Bay Packers quarterback Aaron Rodgers last season.

In each instance, senior vice president of officiating Al Riveron said that flags would continue to be thrown when there is "no attempt" by defenders "to break their fall" when they land with all or most of their body weight on a quarterback.

The examples of legal hits showed players rolling off to the side of quarterbacks, or employing the "gator tackle" technique in which the quarterback is pulled over the defender. The video did not cover the most controversial calls this season, including two against Packers linebacker Clay Matthews.

Vincent's statement did not explicitly say the league hopes to reduce the total number of roughing the passer penalties. But he issued a similar clarification Aug. 22 of the league's use of helmet rule after officials threw 51 flags for it in the first 33 preseason games. Penalty totals dropped dramatically thereafter, and there have been only four flags for the helmet rule during the regular season.
