Several members of the committee, which made the rule a point of emphasis in the spring by pinpointing that they did not want defenders to land with their weight on the quarterback, are uncomfortable with the calls so far, particularly the controversial call against the Packers' Clay Matthews after a hit on Vikings quarterback Kirk Cousins, according to a person with knowledge of the committee's thinking. That call negated what would have been a game-sealing interception, essentially costing the Packers a victory in a game that ended in a tie. The league defended the call.
