It's hard to fathom now, but there once was an NFL universe where everything wasn't televised or tweeted. Like, say, in the photo above, taken in November 1964. Details via the Getty Images archive:
"Broncos GM Operates From 'Hot Line Central'; Denver Broncos General Manager Cal Kunz (seated) calls in a draft pick to American Football League headquarters in New York during Saturday's draft session at the Bronco office. Watching are Coach Mac Speedie (left), defensive line coach Ray Malavasi, personnel director Bill Meek and Paul Manasseh, Don Smith of front office staff."
So not only did the AFL draft used to take place during the fall, there was also a "hot line central" for calling in the picks. Fancy.
As for who the Broncos got with the '64 haul, we turn to our good friends at ProFootballReference.com:
Of those 26 picks, the Broncos landed two Hall of Famers -- defensive back Paul Krause and wide receiver Bob Hayes. Unfortunately for Denver, Krause was also drafted in the second round by the NFL's Washington Redskins, where he led the league in interceptions as a rookie. Similarly, Hayes was selected by the NFL's Dallas Cowboys, where he played 10 seasons.
The Broncos, meanwhile, went 2-11-1 in '64. If only they had Tim Tebow.
