What it is

A juke is a quick fake that makes a defender move the wrong way. The ball carrier steps one way, then cuts sharply in the other.

In a game

It is the main way a runner avoids a tackle in open space. A good juke uses the head, the shoulders and the hips to sell the fake.

More detail

The move works best when the runner does not slow down, because a defender watches the hips. Other tools include the spin move and the cut, which is a sharp change of direction that can be made at full speed.
