Bill Arnsparger, the Miami assistant coach who directed the "No-Name Defense" that helped the Dolphins win Super Bowl titles in 1973 and 1974, died Friday. He was 88.
The Dolphins confirmed Arnsparger's death. The team didn't provide a cause of death.
Arnsparger left the Dolphins after the 1974 Super Bowl to coach the Giants, going 7-28 before he was fired after an 0-7 start in 1976. He returned to Don Shula's Miami staff and remained with the Dolphins until 1983, helping them reach another Super Bowl.
"I was saddened to learn of the passing of Bill Arnsparger, who I thought was one of the greatest defensive coaches in football," Shula said in a statement.
