How to defend a fast-break

What is the way to stop a fast break offense? Are there any tips for this?

I was looking for something on this site but couldn't find it... maybe Jeff and Joe can show you what they have.... I did a quick search and came up with these.

I'm not sure what age group you work with... but for younger kids a simple way is to jam the rebounder... find their point guard - try to deny him the ball or at least force him to go back to it.. and eveyone else hustles back, covering the paint first - NO easy layups.

Thanks! I will will have a look at it.
