I teach it in terms of lines. I want our OF to throw a line to his target to get there with velocity.
If the OF has thrown a good line with velocity on target we say nothing and our relay man will fake a cut. We want no more than 2 hops. Anything more than 2 hops is a weak throw which gets us to the next one...
If the line is weak or off target have the receiver yell RELAY because it continues the line to the original target. We are getting the line back on target or creating velocity because the OF didn't provide it
If we want a throw to go to another base we call CUT 2,3,4 because we are changing the line and have to create a new destination
If there is no play whatsoever then it's CUT HOLD and now we are stopping the line
