A look at the NFL's second decade, the 1930s:
FRANCHISES
The 1930 season was played with 11 clubs, including the Portsmouth Spartans - who became the Detroit Lions in 1934 - the lone newcomer. It also marked the final season for the Minneapolis Red Jackets and Newark Tornadoes. The Frankford Yellow Jackets and Providence Steam Roller left the league after 1931. It was also the first (and only) campaign for the Cleveland Indians. The league dropped to eight members in '32, including the new Boston Braves - who became the Boston Redskins in 1933 before moving to Washington four years later.
