If this were to happen, would zone blocking in the running game be finished? Don't you need to go low on backside pursuit for zone blocking to be effective?
According to a recent report by Sports Illustrated, however, the NFL competition committee will consider banning all blocks below the waist in 2013. There's no guarantee it will pass. But if it does, there could be significant pressure on college football to take a similar step — even if there's no clear consensus that it would reduce injury risks
