Bob Costas is synonymous with NBC Sports. For 40 years, he has been the voice of some of the most iconic moments in sports. From the Olympics, to NFL and NBA, he has had a front row seat to sports history. Before that, he was the voice of the Chicago Bulls on WGN in 1979. In the first episode of “Chicago Unscripted,’ Costas covers everything from politics, to his classic call of ‘The Sandberg Game,’ his memories of Harry Caray, the 1972 Olympics, his exit from NBC, and his Mount Rushmore of sports broadcasters.
