Since 1951, nobody has had a better rush defense than the 2000 Ravens. Anchored by future Hall of Fame middle linebacker Ray Lewis, Baltimore held opponents to a paltry average of 2.69 yards per carry and did not allow a 100-yard rusher all season. They set 16-game records for fewest rushing yards and points allowed, and posted four shutouts during the regular season. They somehow managed to tighten things up in the playoffs, allowing a total of 23 points in four games and holding the Giants without an offensive touchdown as they won the Super Bowl in a 34-7 rout.
