Lewis was celebrated as an iconic figure in Cowboys history, known for his humor, including a famous remark about Texas Stadium having 'a hole in the roof so God can watch his favorite team play.'

In 1984, Lewis was honored on the Cowboys Silver Anniversary Team, reflecting his lasting impact on the franchise.

Despite concerns about his size, standing 6-foot-1 and weighing 225 pounds, Lewis was drafted in the sixth round of the 1968 NFL Draft after earning SEC Defensive Player of the Year in 1967.

Over a 13-season NFL career, primarily with the Cowboys, Lewis played in 186 games and started 135, showcasing his durability and skill.

Lewis's college career at Mississippi State was distinguished, earning SEC Defensive Player of the Year and consensus All-America honors, with legendary coach Bear Bryant calling him 'the best linebacker in the country.'

Initially a reserve in the Cowboys' first two Super Bowls, Lewis became a regular starter from 1973 onward, contributing to four Super Bowl appearances and two championships.

D.D. Lewis was a legendary linebacker for the Dallas Cowboys, playing a franchise-record 27 playoff games and contributing significantly to their Super Bowl victories, including notable performances such as two interceptions in the 1975 NFC Championship Game and a sack in Super Bowl XII.

Lewis's career highlights include his last postseason interception in Super Bowl XIII, and he was one of the first Cowboys players to compete across three decades, earning recognition in both franchise and college halls of fame.

The Cowboys announced the passing of D.D. Lewis at age 79 on September 17, 2025, marking the loss of a key member of their famed 'Doomsday' defense.
