In gridiron football, a dual-threat quarterback, also known as a running quarterback, is a quarterback who possesses the skills and physique to run with the ball if necessary. With the rise of several blitz heavy defensive schemes and increasingly faster defensive players, the importance of a mobile quarterback has been redefined. While arm power, accuracy, and pocket presence – the ability to successfully operate from within the "pocket" formed by his blockers – are still the most important quarterback virtues, the ability to elude or run past defenders creates an additional threat that allows greater flexibility in the team's passing and running game. Overall, the dual-threat quarterback has been referred to as "the most complex position in sports" by Bleacher Report.
