When aggressive defenders go very, very bad

This 17 seconds of defensive hell is a reminder to all defenders to stay between the goal and the person with the ball, unless you are ABSOLUTELY certain that you can at least touch the ball. This defender is fine and then runs in a circle to chase the ball , opening up the goal for an easy score.

This defender needs to be removed from the game, shown the tape of how silly she looks and encouraged to stand her ground, and then put right back in the game. (Would that be legal?)

Aggressive defense protects the goal, with the ball or without.
