NFL commissioner Roger Goodell issued a statement on the passing of legendary Miami Dolphins head coach Don Shula, who died on Monday at the age of 90.

Here's what Goodell had to say about Shula's impact on the league as the winningest coach in NFL history:

​”Don Shula will always be remembered as one of the greatest coaches and contributors in the history of our game. He made an extraordinarily positive impact on so many lives. The winningest coach in NFL history and the only one to lead a team to a perfect season, Coach Shula lived an unparalleled football life. As a player, Hall of Fame coach, and long-time member and co-chair of the NFL Competition Committee, he was a remarkable teacher and mentor who for decades inspired excellence and exemplified integrity. His iconic legacy will endure through his family and continue to inspire generations to come. We extend our heartfelt sympathy to Don's wife Mary Anne along to his children Dave, Donna, Sharon and Mike, the Shula family, and the Dolphins organization.”

Don Shula led the Dolphins to the only undefeated season in NFL history. Shula ended his coaching career with 347 wins. He started as the Detroit Lions defensive coordinator before being hired as the Baltimore Colts head coach. He coached with the Colts from 1963-1969 before moving onto the Dolphins.

Before becoming a coach, Shula was an NFL player from 1951-1957 playing for the Cleveland Browns, Colts, and Washington Redskins. He finished his career with 21 interceptions in 73 career games.

This is a sad day for the NFL as one of the all-time legendary figures is gone.
