The NFL is assessing the viability of further rules changes on kickoffs with unprecedented input from the league’s special teams coordinators, who want to save the exciting play from extinction. Dean Blandino, the NFL’s vice president of officiating, recently held a conference call with special teams coordinators from all 32 teams to discuss the kickoff play and ways to make it safer, two people with knowledge of the call told USA TODAY Sports. No rules changes would take effect this fall. But the coaches were told to be ready in the unlikely event the NFL conducts an experiment during part of the 2016 preseason, said the people, who spoke on condition of anonymity because they weren’t authorized to discuss the call.
