MIAMI Jim Kiick, the versatile running back who helped the Miami Dolphins achieve the NFLs only perfect season in 1972, has died. The former University of Wyoming star was part of a formidable backfield that included his best friend, Pro Football Hall of Fame fullback Larry Csonka. In 1975, Kiick, Csonka and future Hall of Famer Paul Warfield left the Dolphins for the WFL. But the WFL folded, and Kiick returned to the NFL for his final two seasons, playing for Denver and Washington. His daughter is professional tennis player Allie Kiick, who has been ranked in the top 150 on the womens tour.
