In 1873, Princeton, Columbia, Yale and Rutgers set forth rules that all colleges who wished to play the sport of football had to follow. But running the football was not among those rules, nor was throwing it. Harvard was absent in protest. The first legal forward pass didn't happen until 1906 after a rule change was made to allow it.
Here we are, 107 years later, and we see a quarterback position our gridiron ancestors wouldn't recognize if it tapped them on the shoulder. Can you imagine if the National Football League did not allow the ball to be forwarded by pass or run? Oh, perish the thought! In some popular formations of yesteryear (Pop Warner's single wing) the halfback was actually the primary ball-thrower and the quarterback was his blocker.
Though the final image in the slideshow will list who I believe best personified the attributes of a mobile, multi-threat quarterback this is not a "best of" list, but rather an abbreviated historical survey of quarterbacks who were, more or less, equally effective at running and throwing the ball.
Many of our fathers marveled at the exploits of "Frantic" Fran Tarkenton of the Minnesota Vikings, while others still recall Seattle's lanky lefty, Jim Zorn. Both also amassed critical yards with their arm and feet. Bobby Douglass of the 1972 Chicago Bears deserves mention as well. His single season QB record for rushing yards of 968 yards stood for 34 years before it was broken by, who else, Michael Vick. Major shout-outs to Doug Flutie, and Roger Staubach, minor shout-outs to Vince Young, Seneca Wallace and Tim Tebow.
