The Miami Dolphins franchise has been a so called laughing stock of the NFL since Dan Marino retired. Before Marino retired the Dolphins were one of the most respected teams in the history of the NFL. One reason for that is because of Dan Marino and the other is Don Shula. Shula who coached the Dolphins from 1970-1995 made the team into a winner.
During his reign as head coach, the Dolphins went to four Super Bowls and won two of those, including the only perfect season in NFL history in 1972. Without Shula as the head coach, who knows how good the Dolphins would have been.
