About Harvey Martin
Harvey Banks Martin was an American professional football player who was a defensive end in the National Football League (NFL) for the Dallas Cowboys from 1973 until 1983. He starred at South Oak Cliff High School and East Texas State University, before becoming an All-Pro with the Cowboys. In Martin's junior year (1967) in high school, he transferred to South Oak Cliff High School, which had become the first integrated high school in Dallas. During his first years with the team, the coaching staff looked to instill in Martin a sense of aggressiveness, confidence and mental toughness, that didn't come naturally to him. By the third game of his senior season, he was a starter and became the best lineman on a 12–1 team that won the Dallas City championship and went on to the State quarterfinals.
