Joe Vrankin helped preside over one of the largest sports league expansions in history during a nearly nine-year run as chief operating officer of the Arena Football League and its subsidiary, the Arena Football League 2. Vrankin talks about the details of league expansion, how the AFL changed during the 2000s to its eventual demise under a strike-riddled 2007 campaign as the collective bargaining negotiations became intense. Vrankin discusses some of the innovations of the old AFL incarnations, including miking the coaches during broadcast interviews and the NBC league ownership model. Twitter: @JVrankin
