1. choose a smart matchup: someone you can cover but be conscious of not sticking your teammates with a bad choices.
2. silently count # of your choice from the left (yell "hold line" if the opposition is moving around)
3. say that # loudly when one of your teammates says the number before
4. if 2 people say the same # call "two <#>s" and quickly determine who is the better match, then move on.
5. When we hear "seven!" (or "sept!") we know that everyone has actively committed to an intelligent choice on defense, and are ready to pull.

Both competitive and pickup teams all over the world use this procedure and can typically complete it in under 15 seconds.
