This week, we offer a refresher course in the history of forgotten pro sports leagues with veteran newspaper editor, current long-form author and fellow defunct sports enthusiast Stephen Provost – whose recent book A Whole Different League is an essential primer for anyone seeking an entrée into the genre.

Provost serves up a smorgasbord of highlights gleaned from his personal memories of and research into the various nooks and crannies of what "used-to-be" in professional team sports, including:

• The curiosity of 9,000 Los Angeles Aztecs NASL soccer fans in a cavernous 100,000-seat Rose Bowl;
• The oft-forgotten Continental Football League of the late 1960s, operating in the shadows of the mighty NFL and colorful AFL;
• The enigmatic one-season wonder of the 1961-62 National Bowling League;
• Jackie Robinson's almost pro football career;
• Federal League all-star Benny Kauff and the major league baseball career-ending auto theft he didn't commit; AND
• The legend of the World Football League's Jim "King" Corcoran – the "poor man's Joe Namath."

PLUS: we revisit the story of women's pro basketball pioneer (and "Good Seats" episode #28 guest) "Machine Gun" Molly Bolin (Kazmer), the subject of Provost's new biography, The Legend of Molly Bolin: Women's Pro Basketball Trailblazer.
