Cloyce Kennedy Box was an American football player and businessman. He played five years in the National Football League with the Detroit Lions, was a member of NFL championship teams in 1952 and 1953, was selected as a second-team All-Pro in 1950 and a first-team All-Pro in 1952, and played in the 1951 and 1953 Pro Bowl games. On December 3, 1950, he set Detroit team records with 12 catches, four touchdown receptions, 24 points, and 302 receiving yards. He later became a successful businessman in the oil and gas business in Texas.
Box played professional football at the end and halfback positions in the National Football League for five seasons with the Detroit Lions from 1949 to 1950 and 1952 to 1954. As a rookie in 1949, Box appeared in ten games, principally as a halfback. He rushed for 62 yards on 30 carries and caught 15 passes for 276 yards and four touchdowns. Box later recalled: "I probably was the worst halfback in the history of the league." In 1950, Box's second year in the NFL, Detroit's coaches sought to take advantage of Box's speed and converted him into an end. Teaming up with Lions' quarterback Bobby Layne, Box appeared in 12 games and ranked among the league's leading receivers with 50 receptions, 1,009 receiving yards, 11 receiving touchdowns, 84.1 receiving yards per game, and 1,009 yards from scrimmage. On December 3, 1950, in a game against the Baltimore Colts, he set Detroit team records with 12 catches, four touchdown receptions, 24 points, and 302 receiving yards. His 302 receiving yards against the Colts was the second highest in NFL history at the time and currently ranks fifth in league history. After the 1950 season, Box was selected by the Associated Press as a second-team end on its All-Pro team. In February 1951, with the Korean War ongoing, Box was recalled from inactive reserve status by the United States Marine Corps. He missed the entire 1951 season due to military service. In June 1952, after being discharged from the Marine Corps, Box returned to the Lions. Box was the leading receiver on the 1952 Lions team that won the NFL championship. On October 19, 1952, he led a comeback victory over the Los Angeles Rams, with touchdown catches covering 64 and 10 yards. He led the NFL with 15 receiving touchdowns, ranked second in the league with 90 points scored, and again ranked among the league leaders with 924 receiving yards, 22.0 yards per reception, and 924 yards from scrimmage. In the 1952 NFL Championship Game, a 17–7 victory over the Cleveland Browns, Box was used mainly as a decoy but was credited with a key block on Doak Walker's 67-yard touchdown run. After the 1952 season, Box was selected by the AP as a first-team All Pro player and was selected to play in the 1953 Pro Bowl. In 1953, the Lions won their second consecutive NFL championship, though Box's receiving statistics declined significantly with only 16 receptions for 403 yards. He was reportedly "robbed of his blinding speed by a leg injury," though he did manage a career-long 97-yard touchdown reception against the Green Bay Packers on Thanksgiving Day 1953. In the 1953 NFL Championship Game, he had four receptions for 54 yards. In 1954, Box's final year in the NFL, he appeared in 11 games but caught only six passes for 53 yards. Over the course of his five years with the Lions, Box totaled 129 receptions for 2,665 yards and 32 touchdowns.
Business career and later years
After retiring from football, he had a long career in business. He began in 1954 as an assistant manager in the Dallas office of the George A. Fuller Company, eventually serving as chairman of the board. He became president of the Oklahoma Cement Company and president and chairman of OKC Corporation, which later became known as the Box Energy Corporation. He also served as chairman of the board of regents for West Texas State University and the Texas Board of Penal Corrections. His Cloyce Box Ranch was used as the original Southfork Ranch for the mini-series that became the first season of the television series Dallas. Box and his wife, Fern Virginia Box, had four sons Don, Gary, Thomas and Douglas. And later married his second wife Ashley Scott Box. They lived in Frisco, Texas, for more than 30 years. Box died at his home in Frisco in 1993 at age 70.
