New England, 3,165 yards, 1978
Doubt it will be broken any time soon. the Giants only have a little over 2,000 yards 14 weeks through the season and they are a running machine in terms of rushing stats per game. A team would have to average 200 yards per game to break the current record. that would be tough to do.
Give us a breakdown of the players involved. A game-by-game summary would be even greater.
