Jim Kiick, the versatile running back who helped the Miami Dolphins achieve the NFL’s only perfect season in 1972, has died at the age of 73, the team announced Saturday.

No cause of death was specified by the Dolphins, however his daughter Allie, a profession tennis player, revealed that the two-time Super Bowl winner had been diagnosed with early-onset Alzheimer’s disease three years ago.

The former University of Wyoming star was an integral member of the 1972 Dolphins team that went 17-0 and won Super Bowl VII, before retaining the trophy the following year.

Kiick was part of an iconic and formidable backline that included his best friend and Pro Football Hall of Famer Larry Csonka and Mercury Morris.

Kiick and Csonka were often coy on the obvious question of which one was Butch Cassidy and which was the Sundance Kid.

‘Same answer I tell everybody,’ Kiick once told a reported. ‘I was the better-looking guy. Whether it’s Butch or Sundance, which was Paul Newman and Robert Redford, either way, you couldn’t lose.’

Kiick – or ‘Butch’ – was a fifth-round draft pick in 1968, spending the first seven of his nine NFL seasons in Miami – making the American Football League All-Star team in his first two years.

He ran for 3,644 yards and piled up another 2,210 receiving with the Dolphins, scoring 31 total touchdowns. His 28 rushing touchdowns are sixth on the Dolphins’ all-time list, with teammates Csonka and Morris among the few ahead of him.

Kiick had two touchdowns for the ’72 Dolphins in the AFC championship game, and also scored in the Super Bowl victory that capped their 17-0 season under Pro Football Hall of Fame coach Don Shula.

Kiick also was an excellent blocker and a threat as a receiver. He had 233 career receptions for 2,302 yards.

After the club repeated the following season, Kiick played one more season, in 1974, then left for the Memphis Southmen of the short-lived World Football League with Csonka.

But after the WFL folded during the 1975 season, Kiick returned to the NFL and played with the Denver Broncos and Washington Redskins over the 1976 and ’77 seasons before retiring.

In all, he finished his NFL career with 3,759 yards rushing, 2,302 yards receiving and 33 total touchdowns.
