“His talent and passion left an indelible mark on the sport, and his three Pro Bowl selections only solidified his place among football’s greats,” the statement read.
Known for his speed and dynamic running game, Morris rushed for a career-best 1,000 yards and 12 touchdowns during the historic undefeated Super Bowl winning season in 1972.
Morris, along with Hall of Fame fullback Larry Csonka who rushed for 1,117 yards, became the first two backs on the same team in NFL history to rush for 1,000 yards in the same season.
The following season, Morris rushed for 954 yards and 10 touchdowns to help Miami win back-to-back Super Bowl titles.
Morris and other members of the 1972 team would pop champagne to celebrate after the last unbeaten team in a season lost.
“Morris left a lasting impact through his dynamic play, personality and record-breaking performances,” the Dolphins said in a statement. “He loved the Dolphins, the fans and the community of South Florida and will forever be remembered as one of the greatest players to don the aqua and orange.
“Our hearts are with his family, loved ones and teammates as they honor his life and mourn his passing.”
A Star in Miami
Drafted by the Dolphins in the third round of the 1969 NFL Draft, Morris played seven of his eight NFL seasons in Miami, finishing with 4,133 career rushing yards and 31 touchdowns. He was a vital part of the Dolphins’ backfield alongside Csonka and Jim Kiick, the trio forming a formidable rushing attack that helped Miami to two Super Bowl titles.
Morris is fourth on Miami’s all-time rushing list with 3,877 yards, behind Csonka (6,737), Ricky Williams (6,436) and Ronnie Brown (4,815).
The 1972 Undefeated Season
The 1972 season was a special one for Morris and the Dolphins. The team went undefeated, culminating in a Super Bowl victory over the Washington Redskins. Morris played a key role in the team's success, leading the NFL in rushing touchdowns with 12. His 1,000-yard rushing season made him and Csonka the first two backs on the same team in NFL history to achieve that feat in the same season.
Morris’s contributions extended beyond his individual stats. He was a vocal leader on the team, known for his passion and determination. His ability to inspire his teammates was crucial to the Dolphins’ success in 1972.
A Legacy of Excellence
Morris’s career was marked by success both on and off the field. He was a three-time Pro Bowl selection and a member of the Dolphins’ Walk of Fame. After his playing days were over, he became a motivational speaker, sharing his story and urging others to avoid drugs. He was a strong advocate for his 1972 teammates, often reminding people that they were the first, and still only, undefeated team in NFL history.
Morris’s legacy is one of excellence both on and off the field. He was a great player, a devoted father, and a pillar in his community. He will be remembered for his talent, his passion, and his unwavering commitment to the game of football.
A Lasting Impact Beyond the Game
In 2013, Morris was added to the Dolphins' Walk of Fame. He was a beloved figure in Miami, known for his infectious personality and dedication to the community. But his impact extended far beyond football, and his family’s statement reflects that sentiment.
“Beyond the field, Mercury was a devoted father, a loving brother, a loyal friend, and a pillar in the community,” the statement read. “His presence extended far beyond football, as he touched the lives of many throughout his time in Miami.”
Though his career ended in 1976, Morris never truly left the game of football. His love for the sport, and particularly for the Dolphins, remained strong. He continued to be a vocal supporter of the team and a source of inspiration for generations of players and fans. He is remembered as one of the greatest players in Dolphins history, but also as a dedicated husband, father, and member of the South Florida community.
Morris' passing is a loss for the Miami Dolphins organization, the NFL, and the entire community. He will be missed but his impact on the sport and the lives of many will continue to be felt for years to come.
