Beginning in 1966 the Newspaper Enterprise Association (NEA) annually awarded the George S. Halas Trophy to the NFL's outstanding defensive player. (The George S. Halas Trophy should not be confused with the Pro Football Writers Association's George S. Halas Courage Award or the National Football League's George Halas Trophy that is awarded to the NFC champion.) The winner was released via the NEA news service and also appeared in the World Almanac, which was an NEA publication. The award ran though 1996. It was considered one of the major awards and as included in the official publication of the National Football League NFL Record and Fact Book and its winners still appear in the NFL's Official Encyclopedia, Total Football II. In his book, A Thinking Man's Guide to Pro Football, sportwriter Paul Zimmerman touted the NEA for its All-Pro team and its awards, since they involved polling the players, rather than being a sportswriter's poll like the AP, UPI, and the PFWA.
