Today is a sad day.

Coach Don Shula, the NFL’s winningest coach who led the Miami Dolphins to the league’s only undefeated season, has died. He was a unique man who exemplified true greatness in every aspect of his life. He was 90.

The Dolphins issued an announcement announcing that Shula died “peacefully at his home.”

Shula won an NFL-record 347 games, including playoff games. He coached the Dolphins to the league’s only undefeated season (17-0) in 1972, culminating in a 14-7 victory over the Washington Redskins in Super Bowl VII.

Our deepest thoughts and prayers go out to Mary Anne, along with his children Dave, Donna, Sharon, Anne, and Mike.

Shula, who also played seven NFL seasons as a defensive back for the Cleveland Browns, Baltimore Colts and Washington Redskins, was inducted into the Pro Football Hall of Fame in 1997.
