using the foot question

[coachgbert]

A coach question, can someone explain what "intentionally" striking it with leg or foot means please? I have been in games lately where that is called a lot, especially if the offense makes a bad pass and it deflects off the thigh, knee or shin of a defensive player. The ref will call a kicked ball and it returns to the offense. Seems like it is a bad pass to me and the defense is penalized for getting in the way.

I still can't seem to get a handle on how and when this is called. Any explanation would be appreciated so I can teach it correctly to my girls.

thanks,
Coach Gbert
