The NFL owners passed two safety-related rules Tuesday at the NFL Annual Meeting in Phoenix. One rule would ban peel-back blocks, and the other would keep teams from overloading one side of the defensive line on point-after and field-goal attempts. Still at issue is the controversial rule proposal to ban crown-of-the-helmet hits by ball carriers. The peel-back or chop block would be outlawed inside the tackle box by the approved rule change. Such a block would be a 15-yard penalty. This likely will be known as the “Brian Cushing Rule,” after the Houston Texans linebacker who suffered a season-ending knee injury last season on an inside chop block. “If my injury further prevents other injuries, then that’s success and there can be some good to come out of my injury,” Cushing recently said. “Hopefully, my injury does change the rule and in the future will prevent tons and tons of knee injuries.” The overload rule was created because kick defense teams were rushing through the gaps created by lining up more defensive players than the offense could block. Defensive teams now can have just six or less players on each side of the snapper at the line of scrimmage. Players not on the line can’t push teammates on the line into blockers, either.
