I am watching the Clemson game, pulling for the ACC. Mid 3rd quarter after the Mutts scored they kicked off. The ball went over the head of the Clemson player and into the end zone but not out of the back. The ball came to rest I the end zone, without being touched or downed. As soon as the ball hit the ground whistles blew and the players ran off the field. Am I missing something or doesn't the ball have to be downed ? Why was it blown dead ? Is there a new rule I don't know about ? Couldn't the Mutts have recovered it for a TD ?
