FILE - In this April 18, 1943, file photo, Fred Mandel, foreground, president of the Detroit Lions, and Charles "Chile" Walsh, assistant coach of the Cleveland Rams, look over prospects at the player draft of the NFL in Chicago. The number of rounds fluctuated through the years, in part because of competition from the All-America Football Conference in the 1940s, but also because college football grew and more players were available.
