A good drill for [tag]flag football coaching[/tag] is Protect the Flag. Lineman need to learn to hold a block – both in pass protection and on run blocks. 
What you need – This is a [tag]football[/tag] [tag]drill[/tag] that can pit offensive and defensive lineman against each other. However, if you are trying to teach the basics of sustaining a block, you might try it with a [tag]coach[/tag], or with other offensive linemen.
How this drill works – To start, the defensive lineman (or coach) should line up opposite the offensive lineman. When the whistle is blown, the offensive lineman engages the defensive lineman and must protect the flag that is set up on a pylon behind him.
The [tag]offensive lineman[/tag] continues to block and pancake the defender as long as he is coming after the flag. This will continue until the coach blows the whistle, or the defensive player gets the flag. The offensive lineman must follow the [tag]defensive lineman[/tag] wherever he goes in order to protect the flag.
You can pit the offensive and defensive linemen against each other in a competition with this drill.
Result – Ideally, the result is to get the offensive lineman to maintain the block and stay prepared – even if their man is down on the ground. Protecting the flag for up to 10 seconds is a good way to reinforce that skill.
