Without a doubt, the most important skill for an NFL quarterback is his ability to throw the football. However, quarterbacks who can run the ball add a whole new dynamic to their team's offense. Quarterbacks being a dual threat is becoming more of a necessity in the modern NFL. Anthony Richardson has burst onto the scene in his first two NFL games with three touchdowns on the ground. Quarterbacks are getting bigger, stronger, and faster, and they are sometimes being used like running backs. However, Richardson left both of his first two games with injuries, demonstrating the risk of utilizing your franchise pass thrower as a running weapon. There have been many quarterbacks before Richardson who excelled running the football. Here are the 15 greatest rushing quarterbacks in NFL history.

15. Donovan McNabb

Donovan McNabb wasn't known for being a premier rushing quarterback at any point in his NFL career, but he stuck around long enough that he put up solid numbers as a runner. McNabb finished his career in the top 10 all-time in rushing yards by a quarterback with 3,459, making him more than worthy of being on the list of the greatest rushing quarterbacks ever. He even had 29 touchdowns on the ground to boot.

14. Bobby Douglass

While most of the quarterbacks on this list were better pass throwers than rushers, Bobby Douglass was more of a true running quarterback. Bobby Douglass only threw for over 1,000 yards four times in his career, yet he stuck around for 10 seasons because he was great with his feet. Douglass had 2,654 rushing yards and 22 rushing touchdowns before it was cool for a quarterback to run the football. Douglass' 6.5 yards per carry are the second most of all time.
