From an NBA Assistant Coach:
What I have found at this level is that players use every advantage they can find to be the best they can be. The art of faking is important to the point guard position as they have the ball in their hands a large percentage of the time. The best players in this league have mastered not only the eye fakes but also:
*the pass fake
*the head fake (as part of the shot fake)
*the foot fake (jab step)
*the voice fake (“use me, use me” — then they slip the screen)
