In an April 2013 article, football analytics website Cold Hard Football Facts named the 1944 Giants the "Stingiest Defense in NFL history,"[1] as the team only surrendered 75 points in ten games.
"The manpower shortage on NFL fields created a variety of statistical anomalies on both sides of the field," said the article, "and the 1944 Giants are no exception.
But even then, the 1944 Giants were a truly awesome unit: the average team scored 18.0 points per game in 1944, well above the 7.5 PPG average surrendered by the Giants.
But even the best defenses can’t get it done alone: Giants quarterback Arnie Herber threw four interceptions in New York's 14–7 NFL title game loss to Herber's former team, the Packers.
