Don Shula, the National Football League’s all-time winningest coach and the iconic longtime coach of the Miami Dolphins, died Monday at the age of 90. The franchise announced the news on its website and said the “patriarch” of the team for 50 years had died “peacefully” at his home. Shula’s teams appeared in six Super Bowls, and he won two. His leadership of the 1972 Dolphins to a perfect regular-season record is considered one of the greatest streaks in professional sports. A representative close to the family told the Miami Herald on Monday that Shula’s death was not related to the coronavirus pandemic gripping South Florida.
