Miami Dolphins Hall of Fame coach Don Shula died on Monday morning at the age of 90, the franchise confirmed in a release on Twitter.

“Don Shula was the patriarch of the Miami Dolphins for 50 years,” the Dolphins said in their release. “He brought the winning edge to our franchise and put the Dolphins and the city of Miami in the national sports scene. Our deepest thoughts and prayers go out to Mary Anne along with his children Dave, Donna, Sharon, Anne and Mike.”

Shula was one of the most notable coaches in NFL history, posting a career record of 328-156 in 33 years roaming the sidelines for the Baltimore Colts and the Miami Dolphins. While Shula won an NFL Championship in 1968 with the Colts and two Super Bowls with the Dolphins, no season stands out more than the 1972 season.

In 1972, the Miami Dolphins posted a perfect 14-0 record and won the Super Bowl with a 14-7 win over the Washington Redskins. Since that season, no NFL team has ever gone undefeated and won the Super Bowl, despite a few teams coming close at times.

“When I looked at the Dolphins, I saw a chance to take charge of a franchise that hadn’t won many games since they entered the AFL and build them into a winning organization,” Shula wrote on the Dolphins’ website in February of 2020. “I knew there was an opportunity to work with some great undeveloped talent there to start that process, so that helped me decide to come to Miami.”

Shula’s coaching career began with the Detroit Lions as a defensive coordinator in 1960. He didn’t remain there long, though. After just three seasons with the Lions, the Baltimore Colts hired him to be the head coach, where he was from 1963-1969.
