observers arguing that Matson's effectiveness as a running back was diminished by such use. New Cardinals head coach for 1958 Frank "Pop" Ivy took strong exception to such criticism of Matson lining up as a wide out, declaring: "I have heard people say that the Cards stuck Matson out there on the flank as a 'decoy' on pass plays, and then forgot about him. That is absurd. He was sent out as flanker with the idea of throwing to him. But most opponents feared him so much that they doubled up on him. They watched him just as closely when he lines up as running back. They'd double team him if he were sitting up in the grandstand eating hot dogs, just to make sure." Matson finished the aforementioned 1957 campaign as the NFL's sixth most prolific running back, with 577 yards gained in 134 carries, for a 4.3 yard average, with 6 touchdowns. To this he added 20 catches for 451 yards and 3 touchdowns through the air. Following the 1958 season, Matson was traded by the Cardinals to the league's marquee franchise, the Los Angeles Rams, for nine players. Matson would later play for the Detroit Lions and the Philadelphia Eagles, earning Pro Bowl honors six times in his career (1952 and 1954–1958). When Matson retired in 1966, his 12,799 career all-purpose yards were second only to Jim Brown. Matson was inducted to the Pro Football Hall of Fame in 1972. Personal life He married his wife Mary, whom he met when both were San Francisco teenagers in the mid-1940s, in 1952. He and Mary lived in the same Los Angeles home from the time he played for the Los Angeles Rams until his death. In his later years Matson had dementia (he had been mostly bedridden for several years), which was linked to Chronic traumatic encephalopathy (CTE), a progressive degenerative disease, diagnosed post-mortem in individuals with a history of multiple concussions and other forms of head injury. According to his son, Ollie Matson, Jr., due to his degenerative brain disease Matson would wash the family's four cars almost daily and barbecue chicken at 6:30 am during his later years. According to his nephew, Matson hadn't spoken in the four years prior to his passing. Death On February 19, 2011, Ollie Matson died of dementia complications (respiratory failure) surrounded by family at his home in Los Angeles, California.
