The NFL competition committee is proposing a rule to penalize so-called “hip-drop” tackles and a radical change to kickoffs to add more returns without compromising safety. The proposals will be presented to owners at the league meetings later this month, with 24 out of 32 votes needed for approval. The committee didn’t propose any rule changes to limit the use of the “tush push” quarterback sneak that has been so successful for the Philadelphia Eagles the past few seasons or any change to the rule giving the defensive team a touchback if the team with the ball fumbles through the end zone.Possible rule changes
