Lang began playing soccer for a team in the Baltimore Police Athletic League when he was thirteen.
After graduating from high school in 1930, he entered Johns Hopkins University playing football and lacrosse.
Each of these awards was for a separate position, third defense, second attack and out home, showing Lang's breadth of ability in that sport.
In 1932, the Johns Hopkins lacrosse team was selected to represent the United States at the 1932 Summer Olympics.
Over the years, he would work in Baltimore, Cleveland and Chicago, joining teams in those cities as his job with Westinghouse moved him.
Lang and his teammates won the 1938 NSL championship, 1938-1939 St. Louis Soccer League title and the 1939 Peel Cup.
