When we evaluate quarterbacks, the one skill set that is often neglected is the pump fake. The pump fake is a skill that only few quarterbacks can execute, but if done correctly, has the ability to change the course of a game. Perhaps to better understand this, we should perhaps understand why the pump fake is a useful skill for quarterbacks.
Most defensive backs read the eyes of the quarterback in order to anticipate where a they are going to throw. A good pump fake can draw defenders away from the actual spot that a quarterback intends to throw.
