Sad news to share from the NFL as legendary Miami Dolphins head coach Don Shula has passed away. He was 90 years old.

Shula will forever be known as the only head coach to lead an NFL team to a perfect season as the 1972 Miami Dolphins went 17-0 and won Super Bowl VII. The Dolphins won the next Super Bowl title, too, after going 12-2 in the regular season.

Shula is also the winningest coach in NFL history with 347 career wins in the league.

Incredibly, Shula served as coach of the Dolphins from 1970 until 1995.

Shula’s son, Mike, served as head coach of Alabama from 2003-2006 and currently serves as Denver Broncos quarterbacks coach.

The Dolphins issued the following comment confirming the news of Shula’s passing.
