The Pro Football Hall of Fame _ which counts both Staubach and Cowboys coach Tom Landry among its members _ says San Francisco 49ers coach Red Hickey introduced a form of the shotgun offense to the sport in 1960, before abandoning it during the following season. But Landry's Cowboys get credit for bringing it back and popularizing it by positioning Staubach 5 yards behind the center. (AP Photo/File)
